Yup.
bash is mostly compatible with bourne (can run most bourne scripts) which is why /bin/sh is a symlink to /bin/bash on GNU and most other *nix systems.
Bash can run Bourne, but not necessarily vice versa, which can be problematic if, say, moving a Linux script to a BSD or AIX box. I remember something I'd done which used, IIRC, $UID, without realizing it was a bashism, instead of using id -u.
