It's highly unlikely that the trademark holders would take action to defend their trademark, but they would theoretically have the right to do so. Anyway, the worst thing that could ever happen to the author, in my opinion, is receiving a cease and desist letter.

The author is going to change his engine name to ChessGM upon my suggestion.

Good call!

While we're on this subject, what is best practice for naming an engine? I'm writing my own engine (it now can play moves but it's dreadful and not all the moves are legal...) and I want to name it, but most of the good names have been taken. Some of those engines have long since stopped development.

I'm wondering just as more than one person can be called "John", is it not the same here, especially if it's not for profit?

You are obviously free to call it anything you want without this being any issue at all including the most offensive and hilarious names. This only becomes an issue if you want to release it, enter it into competitions or talk about it in public - then it is hard to imagine the advantage of naming it something that already exists. "No, I am not talking about THE Stockfish. I was referring to my own little engine, that happens to be called Stockfish, too."
