You can use a 24 volt supply with a 5 volt stepper without any damage at all. This is achieved by regulating the current with the stepper driver adjustment to a value that the 5 volt motor can handle, the stepper driver will regulate the voltage to 5 volts automatically, that is the whole reason to use current controlled drivers.
