EMF diode placement

I have a control board that utilities a high side driver to switch a 12v load to a solenoid(approx 1.8amps) which engages a small starter motor(generator) - along approx 12 inch of cable. I have put the diode as close to the motor as possible.
The control board runs 4.2v and has a microcontroller and gsm module.

would it be possible to mount the diode on the control board or will this risk exposing the board to the kick back from the motor(s).
