I say nay, as I've cooked a couple amps that way.
When you think about it, you're putting a lot of stress on the B-E junction of the "off" amps power stage.
Unlikely such a connection would injure a MOSFET output type, though. With no bias, an enhancement type MOSFET naturally tri-states. BUT, if it's an older type that uses depletion FET's, you'll have a short on the speaker leads.
