only one way to know for sure...
...try putting them on the car.
I think you'd probably need a different tire though, as the overall rolling diameter for an A8 wheel/tire is likely to be larger than for the RS4. If they're not the same, your speedometer/odometer will be off.

I think you're right about the tires...
Proper plus sizing for an A8 would be 255/35R20, whereas the RS4 comes with 255/35R19. That's a significant difference which would raise the ride height .5" as well as affecting the speedo, as you mentioned.

if your numbers for the A8 are correct....
...the speedo will be 3.8% too slow if he runs the A8 20"ers on the RS4 (i.e. 62.3mph actual, with an indicated 60mph).
This is according to the applet linked below, which I'm assuming is correct.<ul><li><a href="http://www.miata.net/garage/tirecalc.html">tire size calculator</a></li></ul>
