I presume you have configured your linux mail server to not be the authoritative mail server for the contoso.com domain.  It would then hand mails that is cannot resolve to a mailbox name, on to the Exchange server for final delivery.

You could now also configure your Exchange server to also not be auhoritative for the contoso.com domain and have all unresolved mail to the linux server.

This should work but you'd have to be mindfull of potential mail loops.  This is also not a situation which should be in place for long as it can cause management nightmares...

Best of luck!
