I'm not sure how you mean the word 'something' here. If you mean 'nothing' is something in that it is a state, category, or type, then I would agree. On the other hand if you mean 'nothing' has some sort of substance or essence to it then I would disagree. 'Nothing' is just a label, the state it refers to isn't a something. It has and contains no existence or being. (Sorry for using so many alternative words. I wasn't sure which were the best to express the idea).
Perhaps it is useful to have more than concept of 'nothing'. If you suck all the matter out of a container it might be fair to say that there is nothing in the container. This could be called 'relative nothing'.
True nothing could be called 'absolute nothing'. Here there would be no space or time, matter or energy, spirits or gods. Nothing could be said to exist.
