Yes you can go online to the credit card companies website and login to your credit card account online and use a different credit card with enough money on it to pay the payment or balance of the other credit card.
I've done this before when I didn't have enough money at the time in my checking account to make the credit card payment on time.
There was a little interest charged on the other credit card but it was much cheaper than paying the $30.00 late fee I would've owed plus putting a ding on my credit report for being late.
So if you need or want to pay a credit card payment with another credit card you can do so.
