Yes and no...you don't have to anchor the stage of the elevator that's in space once it has achieved a geostationary orbit 22,000 mi up, but the section from orbit to the Earth most definitely needs to be anchored!

  Uh, the cable would have to be 42,164 km long to obtain a geosynchronous orbit. If tethered to the ISS the cable would stretch along the orbit of the space station's path and would either...

  1) uproot the anchor system

  2) break the carbon nanotube cable

  3) haul the space station into a lower or...
