That will work. The radial tubes are thicker than bias ply tubes. And radial tubes will work in bias ply tires, but bias ply tubes will not work in radial tires (too thin and can't handle the heat).

The bigger difference is in the valve stems.

The TR75A works best. The TR440 series valve stems will work as well. The TR75A series includes a brass washer at the base of the valve stem to keep the tube from protruding through the valve stem slot. The Tr440 series doesn't have this washer.

Found this for a tube with the TR75A valve stem:
