According to Richard Feynman who I put this question to back in the 1960's ... no.

It is impossible to tell the difference between space expanding and the speed of light (or if you prefer time) changing.

They are just two different descriptions of the same thing.

But what I prefer about the alternative descrition is that it points out the "where did the energy come from" argument is without basis in science but is rather based upon common human experience.
