Choosing a world server.
Nope, you cannot.
PvP is however not server specific (unless you are talking about WvW) and should be quite possible to do cross-server.

Krall Peterson – Warrior

Was meaning WvW.
My friends do a lot of two things: RP and PvP.
Tarnished Coast is the only place for one of those things. Without having that as a world server, I can’t really ask them to come to GW2. it’d be rude and would just mean my friends would have a terrible time.
