In principle, yes, but there are some caveats.
Your FAA PPL allows you to fly an N-reg worldwide, but is also valid for flight on a G-reg (per the ANO - although honestly I don't know if that provision still exists under EASA). If you want to fly any other reg, you need to follow the validation rules for that specific country.
Furthermore, you need to be current. Three landings at night in the last 90 days to carry passengers.
Then there are specific country rules. For instance the Netherlands forbids NVFR completely. All flying at night is done IFR, which requires an IR. The only exception are things like HEMS and police helicopters, and they operate under a specific permission.
