UNIX is an interface, not an implementation.  You could certainly
implement a UNIX interface (primitive UNIX, anyway) with the Apple II
hardware, although performance would be sub-optimal because of
incredibly brain-damaged I/O hardware.  You'd have to rewrite most of
the kernel anyway so you might as well design it for the target
system.
