Yes. But the word "science" is very broad.

Sciences are generally classified by "hardness" or (perceived) quantitative rigor. In that respect, from "hardest" to "softest," the sciences are usually ranked roughly like this: Math (yes, math is as much a science as anything else), Physics, Chemistry, Biology, Psychology, and the Social Sciences.

Computer Science is, as most things are nowadays, interdisciplinary. As such, it really depends about what aspect of Computer Science you're referring to. Some areas of computer science are more rigorous, and have a lot in common with math and physics. Others, such as "software engineering" etc. fall on the softer end of the spectrum.

With that said, I don't think that all programmers are necessarily "computer scientists." They're practitioners of an art. Just like not all doctors are medical scientists - some are, but most are just practitioners.
