Can I transfer BSC to BEP20?

Excuse me, I have a question regarding cryptocurrency transfers. I'm wondering if it's possible to transfer BSC, which I understand to be Binance Smart Chain tokens, to BEP20, which is also associated with Binance but seems to have a different technical specification. Could you please clarify if such a transfer is feasible and, if so, what steps I need to take to ensure a smooth and secure transaction? I'm looking to make sure I understand the compatibility and process thoroughly before proceeding. Thank you for your assistance.
