I think the term "Delamination" is confusion here, they should coin a new term to address this kind of layer
"Depressilation" may be?
I've never seen a laminated bat come unstuck, there shouldn't be any confusion.
The term 'delaminated' is well ingrained in the industry and has always referred to the separation of a layer of willow on the face from the rest of the bat, usually creating a hollow space between the two that causes a clapping sound when striking the ball.
In answer to the original post, yes it is possible for a new bat to delaminate, it can happen to a bat at any stage unfortunately.
