Yes and no.

Any Ego battery will power any Ego tool, so the 2.0Ah battery will work in any of the lawnmowers, but with (at least) three caveats:

First, the most immediately noticeable impact will be a reduction in performance in moderate to heavy conditions. This looks a little different depending on the mower model you are using. In the older 20" mowers they will more easily and more frequently overload and need to recover for a few minutes before resuming. The newer variable power mowers will not be able to reach their max power to maintain blade speed and may eventually overload and need a few seconds to recover.

Second, the run time will obviously be shorter, and possibly much shorter in heavier mowing conditions. My 2.0Ah will almost outlast my arms in the string trimmer, but in higher power tools can be completely drained in as little as five minutes in the right (or wrong) situations.

Third, draining the battery that fast is a lot harder on the cells than a more typical moderate rate. If used this way regularly this could increase the likelihood of premature failure and will definitely have at least some negative effect on the health of and eventually shorten the life of the battery.

That said, I occasionally use mine in the mower while my 7.5Ah is charging, and aside from the minor inconvenience of having to cut narrower strips of grass at a slower pace I haven't seen any resulting issues with my mower or batteries.
