So long as the capacitor is the same value and voltage rating anything should do the job.

The capacitor feeds a secondary winding on the motor and drives a current in approximate quadrature phase to the main winding. This creates the required rotating magnetic field that carries the rotor with it.

Smaller induction and "squirrel cage" motors create the same effect with several short circuit copper straps in the main laminate stack. See shaded pole motor.
