No, your son cannot stay in the U.S. while waiting for the Form I-130 filed by his wife to be approved. He cannot concurrently file a Form I-485, because his with is not a U.S. citizen and therefore, an immigrant visa is not immediately available to him. He must depart the country in compliance with his authorized stay. Visiting the U.S. after the Form I-130 is filed is risky as your son will likely be denied entry because of immigrant intent.
