You can do it, at least in a windowed emacs:

(global-set-key [return]
                #'(lambda nil (interactive)
                    (message "This is RETURN.")))

(global-set-key [13]
                #'(lambda nil (interactive)
                    (message "This is C-m.")))
;; undo
(progn                                  
  (global-unset-key [return])
  (global-set-key [13] 'newline))


The problem, I think, is that most libraries end up
binding C-m and not [return] (likewise for C-i and [tab]).
So you have to always rebind after some mode has stolen
the C-m key (to [return]).
