No you couldn't. From POSIX.2:
If any of the following conditions occur, the rmdir() function shall return -1 and set _errno_ to the corresponding value: ... [EEXIST] or [ENOTEMPTY] The _path_ argument names a directory that is not an empty directory. (5.5.2.4)
The spec is ambiguous on the original issue, BTW: If the named directory is the root directory or the current working directory of any process, it is unspecified whether the function succeeds or whether it fails and sets _errno_ to [EBUSY]. (5.5.2.2)
