It does look like a blade, with the spline that engages in the fan hub slot near the top (#176). I'd guess that if the fan did come loose and move forward, getting tangled in the cowling's Kevlar containment band made short work of the integrity of the fan. If they go looking for it, it won't be a fan stuck in the ice of Greenland. More likely a 20 mile trail of blades and pieces of cowling.
