Can I buy Binance on KuCoin?

Excuse me, could you please clarify something for me? I've been looking into investing in cryptocurrencies and I came across the Binance exchange. However, I'm wondering if it's possible to purchase Binance tokens, or rather, Binance Coin (BNB), directly on the KuCoin platform. Is there a way to do this, or would I need to first acquire some other cryptocurrency and then trade it for BNB on KuCoin? I'd appreciate any insight you can offer on this matter.
