Is this 10% surcharge similar for commercial/government space flight components? If not, why not? What's different about it?

The problem they have is that the parts they want are only available as commercial standard. If they want it hardened, they need a completely new design to be made around that for which they'll be the only customer. For simple electronics where both designs are produced in volume 10% is pretty reasonable. For this application 100x is more likely if you can persuade someone to make the parts for you at all.

I seem to recall Stuart telling us at some point that "hardening" electronics induces about 10% on top of the cost, at least for milspec and aimed at EMP sort of things.

The RAD hardened custom CPU's are 1/100 the speed of regular CPU's and they don't use regular programming language.
