Any 1st level spell heightened to 2nd level counts as a second level spell for all purposes, including counteract level, what slot it requires to cast, and so on. So I don't see why not.
I took this feat with my Elf Wizard for a 2nd level Longstrider spell (since the feat I took prior to this was from the Primal school), so I could have a permanent 10 foot movement speed boost throughout the majority of my adventuring day.
