Okay I'm just gonna start storming here, bear with me
I will start analyzing the different locks and what sets them apart from one another. And ultimately, what defines a Walker linerlock and a Reeve Integral Lock.
Locks are designs and IMO length, width, thickness and all other possible measurements are not a part of the design itself. I know knives where a linerlock bar is as thick as another knife's framelock bar. There are plenty of lockbacks/midlocks with varying sizes. The functioning parts are different sized but they are all still the same lock.
There is also the cutout/bending factor, if we make a linerlocking knife with a liner so thick it has to be cutout, would it make it a framelock? Would the scales that cover the liners and lock completely be just "overlays" now? IMO it's only a feature that was needed to build the original thick RIL. My Spin has a cutout even though the scales are thin enough that it wouldn't exactly need it, but it still has it. If it didn't have it, would you call it a linerlock just because of that? If you were to call it a linerlock, that would mean that the scales are by definition "liners". This categorization however doesn't fit the definition of "liner/lining"...
A covering for the inside surface of something
...as the scales aren't actually covering the inside of anything.
So the presence/absence cutout alone can't really be a deciding factor either.

But this feature can be achieved with the addition of the Rick Hinderer lockstop alone, so would the addition of a lockstop make it a linerlock? Again a feature that can be found in both locks.

This however is IMO the deciding factor that really sets them apart.
If the lockbar is exposed even to some degree, if you grip it hard enough you can actually squeeze the lock even tighter. On the other hand with linerlocks squeezing the handle hard will have no effect on the locking bars engagement and lock strenght. With SOME linerlocks if you squeeze hard enough you might actually disengage the lock. So in the end the deciding factor seems to be how much the scales/overlays are covering the lockbar.
RIL: The lockbar is completely exposed or it is only slightly covered by an overlay and the overlay still allows the hand to apply pressure on the lockbar making it harder for the lock to disengage.
Walker linerlock: The lockbar is completely covered by a scale on the lockbar side of the handle. Preventing the hand from applying pressure to the lockbar in the way described above.
Just my 0.02.
