Element on ticket but not PAH template

If we have certain data elements appearing twice on hard tickets, but might only want it to display once in the print at home, would it work just to leave off some of the elements from the ticket design in the PAH template?

Fake example: order_no is on ticket design 1234 twice, and the design_sl_nos are  222 and 223. If I just put one form field 222 on the 1234.pdf but no 223, should it still work? Or will that cause an error?
