Are Le + Y interchangeable when using à?

Question

Tu veux venir à la piscine? - Oui, je le veux

Does this mean that y and le are interchangeable when à is used as a preposition? Obviously meaning is slightly changed but would the different meaning make a huge problem?

e.g. je le veux vs je veux y venir

Hi Nathalie,
No, they mean different things.
When you answer -
Je le veux 
it means:
yes, I do  ( simply you agree to go swimming)
If you answered,
Je veux y aller, it would mean:
yes, I want to go there, probably meaning the swimming pool.
Hope this helps!

May I ask something further about this specific question/answer? The lesson states that "y" is used if the phrase starts with "a" (sorry, can't get the accent to work). So I really don't understand why the answer is je le veux. Unless...is it because the phrase is preceded by an infinitive (eg, venir)? Thanks.

I want to (go) 
rather than 
Je veux y aller = I want to go there ( there being the swimming pool)
