Yes, you can use an AMEX (or any other card) as a method of payment and still receive bonus UR points from using the Chase shopping portal. I've seen a number of reports of people doing just that on another forum.
The drawback is that if - for whatever reason - the portal points bonus doesn't post, you really can't ask Chase to help since you didn't use a Chase card to make the payment.
