Diablo IV Early Beta Access

Hello! I have preordered the game for Xbox One and plan on playing in the early access beta this weekend. My wife has requested that I also try to play some on the computer, so I ordered KFC to get a code. If I enter that code on to my battle.net account for my computer, will that mean I can’t use my preorder access on my Xbox since I will also login to my same battle net there?

Thanks in advance,
