No.

Classic and Mac OS X do not "share" the loopback interface or the
loopback address. Classic only ever shared one address with Mac OS X.
This is the primary address assigned in Mac OS X. The primary active
interface that the address is assigned to must be either PPP or
ethernet.

What about multicasting? Would that help?
Nope. If there is no active ethernet (includes airport) or PPP
interface with an address assigned, there is no way to get packets
between Mac OS X and classic.
