I have recently received an old Ryobi cordless rechargeable mower. I
was told the mower works, but it needs a new battery. The correct
battery for the mower is a 24 volt 15 amp/hour battery.
Before buying the correct battery for this mower, I am wondering if I
can safely test the mower first by connecting it up a 24 volt 75 AH
battery that I can borrow.
In theory that should work. But, I would not try to use the mower's
battery charging system. If the larger battery demands more charge
current, this may damage the charger. This also depends on the design
of the charger.

I agree, but I doubt it would hurt the charger.
A battery doesn't "demand" charge current. It is more or less a
constant voltage source with some resistance. And, the charger needs
to be able to deal with a fully discharged battery in any case.
