If your lawyer okays it, then it's fine. If you don't have a lawyer, why are you asking us? Ask your lawyer.

Honestly, the questin is like asking "Is it okay to copy code from another project?" And the answer is the same: if it works the way you want it to work, and you won't get in trouble for using it, then go for it. The way to determine if it works the way you want it to work is to consult a lawyer.

Don't think of legalese as if it were just marketing BS; think of it as an odd programming language for the legal system. When you need Python code written or evaluated, you become or hire a Python programmer; when you need legalese written or evalauted, you become or hire a lawyer. It's as simple as that.
