This is incorrect so I will explain why.
A magnetic storm of charged particles can induce currents in metal objects, which in turn creates a magnetic field around the object. When that field interacts with the storm particles, it exerts a physical force on the satellite that changes its position. Thus an invisible collection of charged particles like solar wind can move a satellite not by direct collision but by electromagnetic forces.
So, yes, a solar storm can push a satellite in its orbit.
I can easily cite proof and book references.
Yep. There are also other effects (electrostatic, f.e.) that could somehow interfere with satellite trajectory, but all that effects are definitely too weak to deorbit satellites from nominal intermediate orbit in a day, and in such way that stallite engines will not be able restore orbit.
