No, they shouldn't be able to delete it.

You should check the permissions of the directory /dev (SysV command is
'ls -ld /dev');  they should be something like rwxr-xr-x with owner bin, root,
or sys.

In general if a user doesn't have write access to a directory then they cannot
delete any files from it.
