Seller can't but depending on what you said he can ask Ebay to remove. There are a number of things you cannot mention, Ebay, Paypal, Cases, Refunds.
That is why when leaving a negative I always recommend making it brief, something like "An Unsatisfactory Transaction" ebay would not remove that.
It is the Red Dot and Stars that do harm to a sellers account.
