[WH40k] Can a follower of Chaos switch patrons? If not, why not?

Yes, they can, but it's rather difficult to do the further down the line you are. 

Remember that the Chaos Gods aren't concious in the way we understand. They are totally bound to their spheres of power and incapable of thinking or acting outside of them. Mortals, on the other hand, are free agents who can act how ever they durned well want. 

The problem lies in the Path of Glory. The further you are (IE the more Gift's you've received) the more in tune you are with your patron. It's harder to go back a step (without becoming a Spawn) than it is to progress further. Once you reach Daemonhood, you are totally suffused with the power of your patron god and can't change. You're still free to act of your own accord, but your daemonic essence is that of whatever god(s) blessed you.

It is far easier, however, for a follower of Chaos Undivided to turn to the worship and dedication of a single patron.
