 Is there a way to pass through an additional IP without burning a small
subnet?

Technically yes.  Realistically no.

You could put a private address on their router and then masquerade it as a
new public IP on the 450.  This tends to cause more hassle then what you
really didn't save.  I've also tried eoip tunnels to things and that
functions but it's such a pain to support.  Just do it the "right" way and
route down to their equipment.
