You *could* write one that just booted up and became a PDP-11

support. Far simpler to use one of the free Unixes. If you were
really, really concerned about not letting anything else run on the
machine, you could say something at a Linux kernel boot prompt like:
boot: linux init=/usr/bin/simh
and simh would run in single-user mode. This would, of course, be
silly.
why silly? if it would work.
Are there
any PDP11 simulators that run "right down on the iron" of
a PC?
As far as I know, there isn't anything that runs directly on the PC
hardware, they all require an OS. However, John Wilson mentioned
something this week on the PDP-11 mailing list that sounds like he's
planning on running directly on the PC HW in a future version.
