If they have access to the message, they can. But the assumption is that the spammer is at the beginning of the flow, not at the middle. He will only create initial headers. Is this a too strong assumption ? Another question I'm trying to answer myself : isn't this a more general SMTP problem ? Does this kind of problem exist for all other headers or is this specific to filters ?
