you need to import a function before it can be called.

Generaly, what I do following: Imports then Functions and after that- rest of the flow

Slightly modified your code to pass LED object for function

import time
from machine import Pin

def my_func(myLed):
    myLed.value(not myLed.value()) # invert boolean value
    time.sleep_ms(300)


led = Pin(2, Pin.OUT)
btn = Pin(4, Pin.IN, Pin.PULL_UP)
while True:
    if not btn.value():
        my_func(led)
        while not btn():
            pass
