If I have a kronecker product A(kronecker)B, is it possible to retrieve A and B? What is the name for this problem?

Idk, but multiplying A by a scalar and B by the inverse scalar would give the same product as A (x) B, so you definitely can't determine them uniquely.

You can identify each kronecker product with a set of all possible tuples a,b that give that product, and derive rules for maps from that set to itself
