I will say that as a professor who occasionally has to refer to this system in front of a bunch of (American) 18-24 year olds, I'm very grateful for this renaming.
After a lot of exposure, I map "coq" in a CS context to the theorem prover and don't find it giggle-worthy, but the reaction of students hearing it for the first time is different. (And outside of that, I'm more likely to think coq au vin, but I'm a cook.)
