As others said it will probably work.

But keep in mind that since it is not designed strictly for CAN, it probably won't have the correct characteristic impedance and so you should probably keep your stubs shorter than the spec allows.

In general, you should keep your stubs as minimal as possible. As Colin mentioned, CAN isn't designed for a star topology and though it is technically possible to do if all your arms are less than the stub length spec (1 meter if I remember right) I certainly wouldn't do that if using CAT6 cable or other cable that is not specifically designed for CAN.

Edit: Looks like CAT6 cable impedance is 100 ohm. That's close enough to CAN (120 ohm) that you can probably ignore my warnings for the most part.
