Not generally.

There are no registered service running on port 81, so
it should be completely safe to allow it.

You should also allow 443 (htts) and 563 (snews).

If your environment (firewall) normally enforces strict Internet access
control rules, then make sure your Squid has the same set of rules if
proxy requests bypasses the firewall rules.
