I don't think it's the same thing because an abstraction is still tangible. For example, "rectangle" is an abstraction for all sorts of actual rectangular shapes you can find in practice. We have a way to define what a rectangle is and to identify one.

A neural network doesn't have any actual conceptual backing for what it is doing. It's pure math. There are no abstracted properties beyond the fact that by coincidence the weights make a curve fit certain points of data.

If there was truly a conceptual backing for these "abstractions" then multiple models trained on the same data should have very similar weights as there aren't multiple ways to define the same concepts, but I doubt that this happens in practice. Instead the weights are just randomly adjusted until they fit the points of data without any respect given to whether there is any sort of cohesion. It's just math.
