You should be able to take part in some of the Daily Missions (the ones not a part of The Taken King). But you likely won't be able to take part in the Weekly Heroic Strike Playlist, as it is a playlist of Strikes including ones a part of The Taken King. The only other requirements for these activities that I'm aware of is being a high enough level and having good enough gear.
