Nope. No reason not to be eating carbs when trying to gain muscle. Yes, you need protein. No, that doesn't mean you can't also eat carbs. In general if you're trying to gain muscle you should be eating quite a bit of carbs (and fat) because the alternative is to make it really hard to eat enough, for no real reason.

Agreed its undoubtedly easier. 40/30/30 or a 40/40/20 etc. Only real reason i can think for OP to do it is part of some form of prep?
