While it's certainly possible, an important factor is the type of conduit and internal diameter. Is is blue with ridges (smurf tube) and meant for low volt? Is it grey PVC or metal conduit meant for electrical runs? Or is it white PVC meant for an in wall vacuum?

Where is the other end?

Smurf tubes will often be a straight run with no interruptions.

Electrical conduit will require an access point every 360° or less. Electrical conduit also often runs to other j-boxes in other rooms.

Vacuum runs will be run like plumbing drains and have branches that lead to a central trunk.

They type of conduit can help determine the best method of running ethernet cable, whether vacuum, compressor or fish. A picture would help.
