Any one know what approximate tolerances are on these things please?
I have a laptop without an adapter which takes a 19 volt 3.2 amp
adapter. I have a 20v 6.5 amp one and wonder how much damage it will
do to the laptop if I try to use it?
The unit does not have a battery to charge so this adapter will likely
be plugged in a lot of the time.
A tolerance of at least 10% would be reasonable, so 19.0 + 1.9 = 19.9
That was 20.9, when I went to school ... ;-)

which is almost 20V. 20V - 2.0 V = 18V for the minimum on the 20V
supply, so you should be just fine.
New math.
