Usually DMA has several stream and channels. In the corresponding table, as long as TX and RX DMA channels are not the same ones for the chosen UART and SPI, yes they can be done concurrently. Beware that IF you want to bridge them and think it can be done fully at HW level, you might be for a learning curve.
