What is the difference between CV axle and joint?

An axle actually consists of two CV joints. These joints allow the axle to transfer the engine's power to the drive wheels at a constant speed while accommodating any travel conditions, including the up and down motion of the suspension and cornering.

Is a CV axle the same as a CV joint?

A CV (constant velocity) joint is a type of flexible coupling, similar - but generally superior - to a universal joint. A CV axle is either an axle containing one or more CV joints, or a mis-named CV joint.
