Yes, they are two different effects. One enlarges you, one treats the weapon as one size larger. There is no overlap for stacking to be an issue.
What about the new Enchantment for weapons called Growing.
This comes from the Pathfinder Companion Guide - Melee Tactics Toolbox Player
GROWING
Price +1 bonus; Slot none; CL 6th; Weight —; Aura moderate transmutation
DESCRIPTION
This special ability can be placed only on melee weapons.
Once per day, a growing weapon is able to grow by one size category, dealing damage as appropriate for its new size and allowing its wielder to affect creatures one size larger than normal with combat maneuvers limited by size. The wielder is able to use the weapon normally without penalty despite its increased size. The weapon remains at its increased size for 10 minutes.
