Yes, everyone can execute /bin/mount, just like everyone can execute
/bin/rm.  But just like everyone can't do:

rm -rf /

everyone can't do:

mount /dev/sda1 /mnt/sda1

(unless fstab is setup so they can)

There are more factors than just who can run the executable, such as
mount's internal checks and the permissions for the block device.
