I would rsvp Yes and contact Mom and say something like "he's actually having his own bday party earlier that day and due to space limitations we could only invite school friends or we would have loved to have Joey come." So Mom has a heads up. Then tell your son to not bring it up at the party, but if it slips out tell him to tell Joey that your mom only let him pick school friends because he couldn't have too many kids come.
