As far as I can tell, the problem isn't that you can't apply GoH to a C4 free night. It's that you can't be use more than one gifted award at a time. So your own C4 would be fine, but somebody else's isn't.
I'm in wait and see mode, though, as I suspect the #1 use of GoH might be to attach to non-status family members' credit card free nights...
