The lens is likely to fit and work, I am not sure of the image quality.
There is one part of the specification that is not in that screenshot and is often not stated. The parfocal distance is usually 45 mm. The Openflexure microscope V6.1.5 is designed to fit 45mm parfocal distance with the slide riser fitted, or should work with the next most common 35mm parfocal distance without the slide riser. The V7.0.0-Alpha2 is designed to work with 45mm only.
The specification does not include the word ‘Plan’, so I would assume that it is indeed achromatic, but not plan. This means that a flat slide will not be in focus all across the slide. How much this matters depends on what you are wanting to look at. If you are planning to scan and tile images then you really do need a Plan corrected objective.
