2 differents computers with 2 differents Adobe program at the same time ?

I see no reason why you could do what you are looking to do. IIRC, but I could be wrong, you are not supposed to use the Same Program at the same Time on the 2 different computers the CC subscription is activated on.

So using PS and Acrobat on one computer and LR Classic on the other should be fine.

Cloud License allows 2 activations at a time http://www.adobe.com/legal/licenses-terms.html
