I've always assumed the P in PAL was for paper tape.
The Wikipedia artile for PDP-8 says that PAL-8 assembled from paper
tape into memory, so the A and L could have been for Assembler and
Loader.
I have a number of different versions of the "PDP-11 Paper Tape
Software" manual, and the earliest one (DEC-11-GGPB-D, March '71)
turns out to be for PAL-11A, and it says it stands for "Program
Assembly Language for the PDP-11's Absolute Assembler" (pg. 3-1).
Someone with a talent for making lists (*cough*Phil*cough*) ought to
compile a comprehensive table with all PAL and MACRO variants.
