Since twilight forest and the nether are disabled in MC ages, then you can't make your way directly back, no.
What you end up having to do, is either make enough books to age-hop your way to star fissures, or you cheat your way back with /tpx, or spawning nether portal blocks in.
Edit - Alternately, have someone link in and save you if you're on multiplayer. Remember that if you're going to age hop, you should bring multiple books, as you can get stuck in ages without cows or reeds.
