No, that wouldn't work since /etc/services is used for connections going
out FROM not incomming.  Potentially you could use such a change to make
your users think that you don't provide telnet service to other hosts or
something bizarre like that but it would be much easier (and more
effective) to remove /usr/bin/telnet if you want that effect.
