Technically the GT 730 would work on a PC that had a Ryzen 5 2400G CPU, but the iGPU on the Ryzen 5 will be faster than the GT 730. You would have less gaming performance if you used the GT 730 than the iGPU in the Ryzen 5 2400G.
ryzen 5 2400g IGPU is nearly 2X better than a 730 GT so why would you downgrade your GPU performance. That APU has a little better than a 1030 GT performance without overclocking.
