Yes, it's available on all sorts of systems, not just Linux.
No, /bin/sh is not bash in all sorts of systems.
Bash has been around much longer than Linux but before Linux, it was not
installed as /bin/sh on any system, and even today it's not installed
as /bin/sh on anything but Linux (and maybe OS X, I'm not familiar
enough with it to know).

We're talking about features that are available in scripts that begin
#!/bin/sh, not features available in scripts that begin #!/bin/bash (or
#!/bin/ash or #!/bin/hush).

At least that's my understanding of the discussion.
