Yes and no is the answer.

The Host Card emulation (HCE) part need to be in Java/Kotlin, the part that enables HCE could be in React Native.

Note that HCE cannot emulate all types of NFC Tags, just Type 4A Tags, I believe there is a react native library to wrap around the HCE part to emulate and even smaller specific custom implementation to match an associated reader App.
