The Hammers are trying to seek an arbitration panel hearing into Carroll's sending off during their 2-0 win over Swansea last weekend.
This week a three-man Football Association appeal's body upheld the decision of referee Howard Webb to dismiss Carroll following a clash with Chico Flores.
Speaking ahead of Villa's Premier League clash with West Ham, Lambert insists he understands West Ham's reasoning.
But the Scot also feels a dangerous precedent could be set the case goes before an arbitration panel as that would give other clubs the opportunity to ignore future FA decisions.
"I don't get involved in somebody else's business. It's up to West Ham and what they want to do," said Lambert.
"I don't know the ins and outs. All I know is they're debating trying to get him off. It's not my remit, it's for West Ham.
"But if is overruled then you create a monster of everybody wanting to do the same. That's what could happen."
Asked whether he would go down a similar route if the circumstances were the same and Villa striker Christian Benteke was in the dock, Lambert added: "It's hard to say. You can understand West Ham trying.
"You'd have to judge the incident on its merit. Everybody is going to be different, whether they think something is dangerous or not. That is their own perception.
"Whether West Ham see they've a chance to get it rescinded, I don't know."
