IMO the anwser to the question is yes but i would say no .
To put it as simply as wind1 did ,You would not use a squash racket to play tennis but you can still hit a tennis ball with one .
When i started i used my wakeboard to kite but after one attemped i dicide to get a secondhand board . Wakeboards are made useing a different construction technic which makes them a lot heavier and more rigged they are designed for a different propose so the fins are generally a lot smaller and in a different position to a kiteboard and wakeboards come in one of two rocker types single or three stage all kiteboard have a very small single stage rocker .(i believe )
To answer your other question yes you can put wakeboard bindings on a kiteboard but it depends on the board .
At one point i was useing a Cab Labrat with wakestyle ankle boot it was great because it gave the extra support but at the same time was easy to get out of . And i think that is the most important thing , if you are getting dragged down the beach the last thing you want to be worrying about is how to get your board off .
