Just finished replacing - stopped at step 23 after removing the Track Pad. Did not have to remove Logic Board. You don’t even need to remove the Track Pad, but because of the glue on the center cell, it’s probably a good idea and a pretty easy step to keep Track Pad safe when prying the cell off the case. It does take a bit of careful “jiggling” to remove the old battery and to slide the new one under the LB, but IMO definitely much (MUCH!) easier than removing all of the components after step 23.
