Answer

No, it cannot

Work Step by Step

We will consider a high body temperature (313 K) and a very low outside temperature (260 K). We find: $e=1- \frac{260}{313}=17 \% $ Even in this extreme example, the efficiency remains much lower than the body's efficiency. Thus, the body is not a heat engine.
