Can someone with an expired visa (making him illegal to stay here) with a arrest warrant be arrested in an airport while leaving

Both TSA and ICE have access to a wide array of criminal investigation information, so there is certainly a chance the person will be stopped, questioned and perhaps placed in custody at the airport. You might advise the person to check with a local lawyer to clear up the pending warrant before departure and to take immediate steps to upgrade status.

You need a lawyer. Check with a lawyer in your locale to discuss more of the details.
