Yes, and of course Linux and GNU are also free UNIX, except they can't call it that because they are not. UNIX is a licensed trademark. You and I could build cars that do everything Chevrolets do*, but we couldn't call them Chevrolets, because they wouldn't be, because Chevrolet is a trademark of GM. Linux and GNU and Free BSD do (almost I suppose) everything UNIX does, but they're not UNIX. (GNU of course stands for GNU's Not UNIX.) The term sometimes used for these systems is UNIX work-alikes.
It's a funny world we live in. z/OS is UNIX and Linux is not. I think Windows Server is also UNIX. *Actually, we would also run into patent problems doing everything Chevrolets do, but you get my point.
