Not that I know of. Here is some information on the numeric keypad
thing:

./emacs-24.5/bin/runemacs.exe -Q
fundamental mode
Trying C-M-e with num key lit: end-of-defun is run
Trying C-M-e with num key un-lit: end-of-defun is run

./emacs-25.3_1/bin/runemacs.exe -Q
fundamental mode
Trying C-M-e with num key lit: € is inserted
Trying C-M-e with num key un-lit: € is inserted

So it had no impact.

Also, on this keyboard the $ sign is on numeric key 4 and @ character is
on key 2. They get inserted by C-M-4 and C-M-2 respectively in the
Notepad editor for example, (simalar to the C-M-e event). The same is
true on my neighbours computer. Thats news to me, I usually use "alt gr
+ 2" for example to insert @. So one could maybe think that those
key-strokes are in the danger zone as well but in both emacs versions
the effect is

C-M-2 runs the command digit-argument
C-M-4 runs the command digit-argument

no insertion of @ or $.
