Well...
 * "psych-/psycho-" - From the Greek for "soul". Used to mean either "soul" or "mind"
 * "tele-" - From the Greek for "at/from a distance".
 * "-kinesis" - From the Greek for "motion/movement". Also has a current common meaning of "manipulation"

In most cases the term is read as "kinesis is the manipulation of  without touching it." Telekinesis and Psychokinesis don't follow that pattern. The first is fundamentally applied as moving things at a distance with out touching them and the second is moving things with the mind.

If were are going by the weight of use in fiction, then both are the catch all for "moving things at a distance without touching them". Writers have used them interchangeably for a very, very long time.

With regard for here, the decision was made to use "tele-" as physically moving objects with the mind and "psych-" as the umbrella for manipulating things a a distance without touching them. Hence pyrokinesis, hydrokinesis, chronokinesis, telekinesis, etc are sub sets of psychokinesis.
