Is it safe to change my URL name?

Hi everyone,

I’ve just installed WordPress with Fantastico, but the name ended up like this: – https://www.lionel1.com/Entertainment/wordpress/wp-admin/.

Dose anyone know if it’s safe to change the (wordpress) to something else?

I would like to change it to:- https://www.lionel1.com/Entertainment/news/wp-admin/

Dose anyone know if this is safe to do? Or better still completely remove the (wordpress) so that it looks like this:-

https://www.lionel1.com/Entertainment/wp-admin/

Anyone know it this is safe to do?

Thanks.
Lionel.
