Nope. A/UX requires virtual memory, which requires an
MMU. Basilisk II does not emulate an MMU. And that's
only one of the reasons why it can't run A/UX, but
it's enough. :)

Basilisk II is more of a Macintosh _simulator_ than
it is an emulator. The only hardware it emulates are
the CPU and FPU. Everything else is based on info
available on how a Mac is supposed to react when an
application or the System does specific things, then
Basilisk replies with the proper response.

That works very well on a computer designed to isolate
applications from direct interaction and control with
the hardware. The Macintosh was designed so that
programmers didn't need to know much about the
hardware. They mainly needed to know the API or
Application Programmng Interface. Apple would take
care of making sure each model of Mac would react
the same to the same commands from applicatons.

A big part of how they did that was to place a good
chunk of code that on other computers was in the OS,
into each Mac model's hardware specific ROM. That
way the System as installed could be "generic" enough
that when installed on one model of Mac it could
also easily work on many different models of Mac
without needing to be renstalled.
