Yes!  Well, at least EARLY 90s   (135W, 150W, . . .)
Until the advent of the ATX boards, PS/2, tower cases, etc., the PC power
supplies were pretty much interchangeable.

Some AT power supplies are too tall for the 5150 case.
Tower case power supplies may need different mounting holes?
Some later power supplies have extra connections for CPU fan, etc.

The power supply may not be testable without a load.  I use a car
headlight bulb.
