Since the shaving cream would be put in the area where checked luggage is stored on the plane while flying then the shaving cream cans should not explode.
Shaving cream cans and other pressurized can would only explode if they were inside the plane itself where you're located and flying due to the pressurization of the airplane.
You can only take shaving cream and other pressurized cans on the plane through the checked luggage and not your carry on so the shaving cream is safe to take on the plane in the checked luggage and will not explode.
