Yes, you can - provided the rest of your network is setup properly.

Every version of Yahoo Messenger I have seen will try its own ports by
default, and if it is unable to use those ports, it will tunnel over
port 80 (or through a configured proxy).

In a proper setup (where the only access to the Internet is via the
proxy), Squid can be used to block Yahoo Messenger quite effectively,
as other list members can confirm.
