I am not an expert, some commands act differently when called
differently; so executing /bin/atq would make the 'at' binary behave
differently than when it's executed as plain 'at'.

The same logic applies to bash, /bin/sh is a symlink to /bin/bash, but
when bash is invoked as sh it acts differently than when invoked as
'bash'. Have a look at the bash manual page for more info.
