Hi there. One of the beauties of Guild Wars and Guild Wars 2 is that you can play from anywhere in the world, as long as you have a computer (with sufficient system specs) and an Internet connection. If you have authentication set up (and I hope you do) simply accept the new system and you’re good to go.
I actually have the game client installed on four computers, and I just log in on whatever system is handy or whichever one I prefer to play on that time. (Of course, if it’s been a while, I need to update, but that doesn’t take long, so no biggie.)
Anyway, thanks for asking, and yes, what you’re suggesting is perfectly fine!
