Not without taking the link down. If you don't mind taking the link down for a little bit, you can run a script locally that telnets into the router, changes the speed/duplex, then tries to ping out. If it can't for more than a minute, telnet back into the box and change the speed/duples back.
Another way is to use a scheduled reload (e.g. reload in 5) and then cancel the reload if the change worked.
