In theory, someone could gain control of the account, but is it really worth jeopardizing one's employment? Elite benefits are allowed as well as all hotel point programs can be kept on personal accounts. Northwest will not combine the business and personal Worldperks accounts for purposes of Elite mileage accrual (bummer!).
There is no such thing as separate business and personal WP account, as per the terms & conditions of WP:
Only one person may be enrolled per WorldPerks account. An individual may have only one account and that must be in his/her real (legal) name. Membership will be listed under the participant’s full name including title (Mr., Ms., etc.) and middle initial. To receive flight credit, the name on the ticket must match the name on the member’s account exactly.
This is no different than an employer obtaining and using a credit card in the employee's name.
