I would say certainly not. In Nova Astronomia in which Kepler lays out his discovery, one finds chapters and chapters (originally in Latin) of verbal analysis of what is going on. He did not just find a formula that worked blindly. Rather he envisioned an influence -- either magnetism or something similar to magnetism -- which he calls specie (a Latin term used in magic and mysticism) extending out from the Sun guiding the motions of the planets. This was a clear precursor to the concept of a gravitational field.
