No, once you have created a profile on a business page it turns in to a personal page. This action cannot be reverted.
From this article on the Facebook Help Centre:
What happens if I click the 'Create Your Profile' button at the top of my
business account?
If you click on the "Create Your
Profile" button, you will be asked to
provide additional information to
allow you to transform your business
account into a personal account. You
will be required to enter your full
name, a security question, and an
answer to your security question. Once
this final registration step is
completed, these changes cannot be
reverted. You will then permanently
have a personal account on the site.
And from this article
If I turn my business account into a user profile, can that action be
reverted?
No, once you provide the final
registration information for creating
a user profile, you cannot revert back
to your business account.
If you convert your business account
into a user profile, you will still be
able to manage all the Pages and
Facebook Ads you’ve created by
clicking the Ads and Pages link in the
left hand navigation menu entitled
'Applications'. The fans of your Pages
will not have visibility or access to
your personal profile. Any actions
that you take as a Page administrator
on your Page will show the Page’s name
as the actor and not your personal
name. However, if you wish to restrict
your privacy so that other Facebook
members cannot find you in search or
add you as a friend, you can do so by
clicking on "privacy" at the top any
Facebook page.
