Apple Watch Sneakout Method?

So if my mom has Life360 and Find My for my phone, could I hypothetically take an Apple Watch to a party while leaving the phone where I'm supposed to be and not have the location update? The idea here is that I could text her back as if I'm at my friends house when in reality I'm at a college party and she wouldn't be able to tell from my location being at my friends house. Does this work?
