Sorry not that I know of.

AFAIK eBay does the determination of who is who and what is linked.

But I am not sure if this is the case, if if is an automated and/or universal process or if it just occurs in an adhoc way.

If you opening an account just to get around your business accounts limits - then I imagine that could possibly be against the rules too.  I opened other accounts to either buy, sell a few household items not related to my business activities at all or to trial different markets or a different selling format.
 

Sorry
