You can probably use the 428 chain on the 420 sprockets. Not the other way around though.
428 sprockets are too thick for a 420 chain.
Depending on the sprocket cut. Not only does the 428 have a wider pin and plates, it also has a roller that sets about .325mm different in the tooth valley than the 420 roller does. (larger roller dia.)
Even though the two chains have the same pitch, the transition from the roller off the working face of the tooth may be enough difference that there may actually be more "noise" when using a 428 on 420 sprockets.
