I have a Holiday Inn Visa which is a corporate card and allows point accumulation.
Also in my previous job, I had an AMEX corporate card. Initially they allowed me to sign up for membership rewards, but later they terminated membership rewards, saying that it violated the agreement with the employer. The impression I got was that some corporations allow cardholders to accrue membership reward points, while some do not.
In your case I do not see why the "ghost card" could not accrue miles which the company could use.
