Benefit: Once per day, when a rogue with this talent hits a creature with a melee attack, she can move up to 30 feet without provoking attacks of opportunity. The movement must end in a space adjacent to the creature hit with the melee attack.
Can I use this talent to move through squares occupied by enemies?
The talent allows you to avoid provoking attacks of opportunity, but it doesn't explicitly allow you to move through squares occupied by enemies. Since it doesn't mention it, the normal rules regarding not being able to move through enemy squares are still valid:
You can still use acrobatics together with Positioning Attack in order to move through enemies.
