At first read I would say "no".
There is a way, but you really do not want to do that.

After reflection, I would like to know WHY you would want to do that. I may have an answer (or two) for you, but which answer is likely to do what you want without untenable risk depends upon your purpose.

Super user or Root is created when you install the OS. Root is the admin of the box.

If you want to give users root privileges to do certain actions then look at the sudoers file.
http://linux.die.net/man/5/sudoers

#visudo
[...]
# User privilege specification
root ALL=(ALL) ALL
#Enter the below line for your superuser(s)
yourusername ALL=(ALL) ALL
[...]

Save it as normal vi editor

Now try login into the system and you would notice the # prompt for the new login.

change uid and gid to 0 (/etc/passwd file)for you user,but it is bit risky
It will work but prefer sudo methaod
