If the stm32 mcu is connected as shown in the figure below,
is there a way to download fw image from the master stm32(STM32WB35) mcu to the slave stm32(STM32L0) mcu?

Not with standard tools. You could implement the SWD protocol to transfer it from WB->L0 at great effort.

Well some of the L0 have a UART interface on the SWDIO/SWCLK pins.
Can probably done far more efficiently, with less code, using a very high speed serial connection.
From a debugger context you'd want to expose SWDIO/SWCLK from each processor to its own set of pins/pads

Thank you for your answer.
Is there an easier code among SWD protocols...?

I'm not sure what you mean. Could you explain it in more detail?

Which bit? How to transfer data over a UART?
