If you mean on the same listing, yes. A bid on the auction automatically and immediately ends Best Offer and all offers and counteroffers expire, so the seller would be unable to accept your offer once you have bid (and if the seller already accepted your offer you would not be able to bid since the listing would end on that occurrence and so no bids could be submitted--unless maybe the two occur within a fraction of a second but in any case there can be only 1 sale in a single-item listing, which all auctions are so you are safe).
