Yes, you can get food poisoning from old butter, though it's more likely to cause an upset stomach or mild digestive issues (nausea, diarrhea) from rancidity rather than severe bacterial food poisoning, thanks to butter's low water and high-fat content which inhibits bacteria. However, if it has mold, a sour smell/taste, or color changes, it's best to discard it to avoid potential foodborne illness from bacteria or heat-resistant toxins, especially if left unrefrigerated for too long.
