I have a ship with Ador Tallon that has the squad command and the squad token. After I resolve the squad command I flip a squad over to not being activated yet. Can I then spend the token on my ship to activate the squad again?

No, because Adar Tallons ability is used to toggle a squadron after you have resolved a Squadron Command, not a Squadron activation. If you use a dial and a token they are a single Squadron Command with +1 to your effective Squadron value. When another ship uses a Squadron Command within range that squadron can be activated again or when you get to the Squadron Phase that squadron can be activated again.

It would be noted that if you just the token(no command dial) you can still toggle the slider but as me.tuoned above if you use both you can only toggle one

It should be pointed out that a ship can only perform 1 of each command per ship activation. See the timings section in the RRG. You can spend both a dial and token at the same time, but you can't spend the same dial and token at different times to trigger the same command multiple times during an activation.
