You can't just send a pwm signal straight to the motor if that's what you're asking. Gear motors are different than servos because you need a motor driver of some kind (servos have drivers built in).

Yes you can use PWM to control the speed of your geared dc motor. You will need something like an H-bridge between your microcontroller and the DC motor to prevent damage to your controller.
