Yep easy enough to do - don't have to take anything off.
If I remember - there is a plastic bush that goes round the clutch lever end of the cable. If this is missing or if the clutch lever hole is elongated it causes the cable to fray.
I used to keep my spare cable in place on the bike with a bag cable tied over each end so that when it did snap and I was riding all I had to do was connect it.
