In science there's a difference between "law" and "hypothesis" and "theory". A "law", in science, is typically a formula that fits the data. For example: Hubble's law states that the relative speed of some astral object is proportional to its distance. That is, objects that are far away seem to move faster than objects that are closer. Hubble's law is an observation that holds under scrutiny. It would be silly to say that Hubble's law explains why objects that are farther away seem to move faster. That's where theories come in (they go beyond describing the facts, and actually attempt to explain why the facts arise). So, in the scientific sense, Moore's law IS a law. It doesn't explain why it holds, but it seems to hold.
