Someone over at dpreview forum claims that pictures from his K20D display less CA than what he gets with the K10D and K7 (using the same lenses). Has anyone else noticed significant differences in CA between different cameras using the same lenses?

There are lots of factors that can make the visibility of CA different. Some digital cameras even do in-camera processing to hide CA artifacts (e.g. newer Nikons) and almost all manufacturers and photo editing software offer some way of doing this at least in post. Maybe you're referring to this.
But strictly speaking, CA is dependent on two things:
1. Lens
2. Viewing magnification
Purple fringing is both lens and medium related. It shows up more on digital but it also depends on the lens design.
