> There exists ready made BLE beacon hardware with accelerometer, which is excellent for an application like this.

I didn't know that and it's a great start. If I get something like the MOKOSmart M1 Ultra Thin Beacon Tag [1], will I be able to send accelerometer data to let's say a Raspberry Pi, process it further, and send a push notification when needed?

You would need to write custom firmware. Which means access at least to the pin mappings. Moko dos not publish them openly. Ruuvi however does. One would also need a Nordic 52 Development Kit in practice. Other devices like ESP32 are not as power efficient but more beginner friendly.
