I have a diametrically different take on this. Using the same components would show you differences in the table itself. But the inherent flaw in this approach is that you put both types of tables on an equal footing when they are really not by virtue of being mechanically and physically built very differently. For example the reason vintage SME arms pair so well with a Garrard is that they have a nice relaxed presentation that matches the forcefulness of the Garrard. On the other hand, relaxed airy presenters like the Linn are more found with tighter bearing tonearms. So the real purpose should be to optimise setups with tonearms and cart based on each turntables strengths and then compare presentations. Else one is doing something akin to making bruschetta with local Sunflower oil. Just won't optimise that bruschetta and give you a true taste of what the inherent dish is like, now will it?

Steven,
What makes a Garrard forceful and a Linn airy? Is it the torque or is it the decoupling/isolation or a combination of all of these? My point is that it is difficult to make comparisons and arrive at conclusions on different turntables and their associated combinations with tonearm and cartridge. I personally would use a blind test with similar levels of cartridge/phono amp sections.
Cheers.
