If you save it as a PDF or email it, then the same constraint applies.
HOWEVER! If you get the seat you want/like, then go ahead and print your boarding card, send it to your phone or email it. Why?
1) It reduces the chance of seat shifting
2) It increases your chance of an operational upgrade.
Good luck, more importantly I hope you have a great and enjoyable flight.
