No. I thought that it was the culprit (and I don't understand how/why
it's present on my laptop).

"/etc/init.d/grub-common" has a "case" statement with

start|restart|force-reload)
log_action_msg "Recording successful boot for GRUB"
[ -s /boot/grub/grubenv ] || rm -f /boot/grub/grubenv
mkdir -p /boot/grub
grub-editenv /boot/grub/grubenv unset recordfail
log_end_msg $?

so "/boot" is being mounted in spite of the "noauto" :(

[You might want to add "x-systemd.auto" to the "/boot" line in
?etc/fstab". "/boot" will be automounted when it's needed.]
