Axew & EV item trading

[Tarhalainen]

Yeah, i was wondering after i get off Driftveil gym, can i go catch Axew or can i do it before? Or do i also need to defeat Mistralton gym before?

And yeah, probably stupid question but couldn't find answer anywhere. So is it possible that my friend can trade me EV items before i defeat E4?
