I was expecting something similar, surprisingly here is what I observed
on my system (with emacs -Q, GNOME and Evince — Document Viewer).

M-x eshell
$ xdg-open ~/Documents/test.pdf
[Nothing happens]

M-x shell
$ xdg-open ~/Documents/test.pdf
[Evince pops up with the PDF]

M-! xdg-open ~/Documents/test.pdf
[Evince pops up with the PDF]

M-& xdg-open ~/Documents/test.pdf
[Nothing happens]

Emacs: 27.1.91
GNOME: 3.38.3
xdg-open 1.1.3+
