i think this one does it...

Charge/Intercept (PvP/PvE)
/cast [nocombat,stance:1] Charge; [combat,nostance:3] Berserker Stance; [nocombat,nostance:1] Battle Stance; [combat,stance:3] Intercept
Use: This macro will Charge the target outside of combat, Intercept when in combat and switch to the appropriate stance to do so.

hmm... i think this swaps stances and charge/intercept...
may not be exactly what you want...
