These would not be qualified as missiles and have their own guidance systems. Having your rocket go and slam into a neighbouring country is not very conducive to putting satellites into space.
When talking ICBM level, the primary difference between a weapon and a peaceful satellite launcher is the little bit that sits on the tip of the rocket - the payload. Early satellites were literally launched on ICBMs, and if memory serves me right, US military still repurposes ICBMs for launching its satellites.
The platform can be repurposed ICBM but the software is dedicated, ICBMs don’t go orbital and their guidance is written for ground range and precise targeting. The inputs and decision paths would be quite different to a rocket’s.
