I have a system I need to hose this weekend anyway, so checked first. I
moved the /root directory to /usr/root, then exited from su - and su
still worked. Then I rebooted into single user mode and got a shell. So
it seemed fine, if mildly inadvisable.

Therefore, as far as I can see and I did check, you can boot into single
user mode without a /root directory.
