This may be related to the boolean limitation on non-manifold geometry.
You can find more information about the boolean modifier and its limitations on non-manifold geometry here.

Cell fracture leaving behind a big square/rectangle set of pieces should be fixed in 4.0.2 with https://projects.blender.org/blender/blender/commit/c9dd5ce4cc1

With that change, 4.0.2 nearly matches 3.6.x behavior for the monkey (it's not perfect because the monkey is not a manifold mesh)
