Generally speaking if they started life as 2 seperate dbs you would need to merge them together so you have one central database. You would then need to put this on one of the laptops and create a remote database to be put on the other laptop. Then you could use something like Hamachi to create a VPN between the two laptops and sync. This is different depending on whether you are pre or post ACT! 7. I would reccomend though that you find a local ACC in your area that could complete this work for you as it will save you a lot of time and headaches in the long run. You can find a list of ACCs for you country/region at act.com.
