Can a Lithium Ion dw9141 14.4 battery be used to replace a DW9094 Ni-Cad used in older XRP?

Yes,but you will need a dual chemistry charger as well.

The Lithium battery has two full height lugs and two half height lugs on the outside of the rectangular connector which prevent inserting in the XRP. Do I/can I remove these off to make it fit?

No. Those are there to prevent you from accidentally plugging the li-on batteries not a NiCAD charger. The charger will not recognize the chemistry, and will charge it wrong (ruining the battery, or possibly causing fire, etc.). If you want a lithium battery, you need the lithium charger. The lithium charger recognizes both chemistries, so it will charge all of your DeWALT stem pack batteries.
