This "dir is empty" information is a quite volatile information and
can change in the next nano-second.
The question is what is the typical use case, i.e., the activity after
knowing the directory is empty?
If it's simply the deletion of the empty directory, then one can directly try:
rmdir 'path/to/dir'
For other cases, I'd go with an already existing check
(though not specified by POSIX):
find -type d -empty
With that, testing for empty output is sufficient:
test "$(find 'path/to/dir' -type d -empty 2>/dev/null)" \
&& my-action
