Finding minimum complexity explanations isn't what finding natural laws is about, I'd say. It's considered good practice (Occam's razor), but it's often not really clear what the minimal model is, especially when a theory is relatively new. That doesn't prevent it from being a natural law, the key criterion is predictability of natural phenomena, imho. To give an example, one could argue that Lagrangian mechanics requires a smaller set of first principles than Newtonian, but Newton's laws are still very much considered natural laws.
