Indeed:
(defun vc-rcs-find-file-hook ()
;; If the file is locked by some other user, make
;; the buffer read-only. Like this, even root
;; cannot modify a file that someone else has locked.
(and (stringp (vc-state buffer-file-name 'RCS))
(setq buffer-read-only t)))

No, it actually checks the RCS status. It doesn't need the `rcs`
executable for that, instead it parses the RCS file.
