The Iron Challenger is free to use the Auction House to make money and buy the occasional White or Gray item. This is allowed. You may even create a banker/auctioneer, provided they only store/post items that the Iron Challenger has earned. However, you may not receive either gold or items from your other characters. It is recommended that you reroll the Iron Challenger on a new server to avoid the temptation.
