I'm a bit fuzzy as to the meaning of your question, but I'll try to answer anyway:

Yes, the developers can do whatever they want with their title. If they want Game Informer to be the first place the audience sees it, they can do that. If they want to schedule a Game Informer cover but announce the game on their own, before the issue goes out, they can do that too. It all depends on which method marketing sees as the most beneficial for their overall strategy.

Just to clear it up I messaged Anrew Reiner just now if the game on GI's February cover has been announced yet. I'll tell you what he says.
