One can play modern tennis with older equipment, and one can play classical tennis with new equipment.
That's why I believe that equipment is not a defining characteristic of modern tennis, although it is a primary enabler. Maybe I am just quibbling and we are all actually in agreement...
Concerning the bolded part, I suppose you could, but, it wouldn't be optimal. In other words, I think Don Budge would play a higher level of tennis with his racquet than Djokovic would, and vice versa.
