HP 41CX Annunciators Become Visible with Long Inputs

Rather than swapping displays, can I swap the two circuit boards between the 41C and 41CX to see whether display issue in the 41CX body is present with the 41C board, or whether the display issue appears in the 41C body with the 41CX board?

Sure, but the capacitor issue is still relevant if one calcuator has a really early display, and the other does not. That won't damage anything, though.
