No. You must assume that neither airline will interline onto the other, because you purchased travel as separate tickets. "Interlining" is a phenomenon that occurs when you are travelling on a single ticket.
You can ask, and you may have your request accepted, but the airlines are under no obligation to accomodate you in this manner.
