There are some who may have either missed the point or perhaps misunderstood the real significance of this accurate usage of the word 'Pharaoh' in the Qur'an.
You see, it is not the case of the Bible mentioning the term 'king of Egypt' that is the issue here, but rather, it is the fact that the Bible refers to this king of Egypt as 'Pharaoh' in Genesis when relating the story of Prophet Joseph (pbuh).
This is historically inaccurate because the king of Egypt during Joseph's time was not called 'Pharaoh'.
This error is not found in the Qur'an whereas the Old Testament and other Jewish scriptures do indeed make this mistake.
Man you sure are wrong!
From the Koran

YUSUFALI: And remember, We delivered you from the people of
Pharaoh: They set you hard tasks and punishments, slaughtered your sons and let your women-folk live; therein was a tremendous trial from your Lord.
PICKTHAL: And (remember) when We did deliver you from
Pharaoh's folk, who were afflicting you with dreadful torment, slaying your sons and sparing your women: that was a tremendous trial from your Lord.
SHAKIR: And when We delivered you from Firon's people, who subjected you to severe torment, killing your sons and sparing your women, and in this there was a great trial from your Lord.

YUSUFALI: And remember We divided the sea for you and saved you and drowned
Pharaoh's people within your very sight.
PICKTHAL: And when We brought you through the sea and rescued you, and drowned the folk of
Pharaoh in your sight.

Surah Al-Baqarah Ayah [49] (Koran 2:49)
And (remember) when We delivered you from Fir'aun's (Pharaoh) people, who were afflicting you with a horrible torment, killing your sons and sparing your women, and therein was a mighty trial from your Lord.

And, for good measure, the Hadith...
Sunan Abu Dawud
Book 24, Number 3619:
Narrated Ikrimah:
The Holy Prophet (peace_be_upon_him) said to Ibn Suriya': I remind you by Allah Who saved you from the people of Pharaoh, made you cover the sea, gave you the shade of clouds, sent down to you manna and quails, sent down you Torah to Moses, do you find stoning (for adultery) in your Book? He said: You have reminded me by the Great. It is not possible for me to belie you. He then transmitted the rest of the tradition.

Sahih Muslim
Book 041, Number 6943:
Ibn Fudail reported on the authority of his father that he heard Salim b. 'Abdullah b. 'Umar as saying: O people of Iraq, how strange it is that you ask about the minor sins but commit major sins? I heard from my father 'Abdullah b. 'Umar, narrating that he heard Allah's Messenger (may peace be upon him) as saying while pointing his hand towards the east: Verily. the turmoil would come from this side, from where appear the horns of Satan and you would strike the necks of one another; and Moses killed a person from among the people of Pharaoh unintentionally and Allah, the Exalted and Glorious, said:" You killed a person but We relieved you from the grief and tried you with (many a) trial" (xx. 40). Ahmad b. Umar reported this hadith from Salim, but he did not make a mention of the words:" I heard".

Book 031, Number 5966:
Abu Musa reported Allali's Messenger (may peace be upon him) as saying: There are many persons amongst men who are quite perfect but there are not perfect amongst women except Mary, daughter of 'Imran, Asiya wife of Pharaoh, and the excellence of 'A'isha as compared to women is that of Tharid over all other foods.

Book 006, Number 2520:
Ibn'Abbas (Allah be pleased with both of them) reported that the Messenger of Allah (may peace be upon him) arrived in Medina and found the Jews observing fast on the day of 'Ashura. The Messenger of Allah (may peace be upon him) said to them: What is the (significance) of this day that you observe fast on it? They said: It is the day of great (significance) when Allah delivered Moses and his people, and drowned the Pharaoh and his people, and Moses observed fast out of gratitude and we also observe it. Upon this the Messenger of Allah (may peace be upon him) said: We have more right, and we have a closer connection with Moses than you have; so Allah's Messenger (may peace be upon him) observed fast (on the day of 'Ashura), and gave orders that it should be observed.

Book 006, Number 2518:
Ibn Abbas (Allah be pleased with both of them) reported that when Allah's Messenger (may peace be upon him) came to Medina, he found the Jews observing the fast on the day of Ashura. They (the Jews) were asked about it and they said: It is the day on which Allah granted victory to Moses and (his people) Bani Isra'il over the Pharaoh and we observe fast out of gratitude to Him. Upon this the Apostle of Allah (may peace be upon him) said: We have a closer connection with Moses than you have, and he commanded to observe fast on this day.
