Cheers.
I checked and my laptop shows the bluetooth as:
HCI Version: 2.1 (0x4) Revision: 0x534fSo it may not support the 4.0 / "Smart Ready" of the one I linked.

This is really at the limits of my knowledge and I wouldn't trust it at all but I believe there are two types of Bluetooth 4.0/BLE module: one type supports only 4.0/BLE and the other that supports both BLE and 2.x/3.x.
I would however suspect that the mouse has support for only 4.0/BLE and even if it didn't battery life would be impacted negatively enough that you'd end up reaching for the dongle anyway.

I have an old laptop at home I can test mine with (if I remember to take it home from the office tonight).

Sorry I phrased my initial reply really poorly. What I meant was that most wireless mice are not Bluetooth despite both using 2.4ghz. A generic 2.4ghz wireless device requires the dongle because it's signal uses a proprietary radio signal and cannot be picked up by a Bluetooth receiver.
The mouse you linked should work just fine without a dongle with you laptop
