Yes you can control the laptop remotely through the AccessAnywhere option within avast.
But for that to happen the one who has the laptop now must be foolish enough to accept the remote control request.
It is not very likely that that will happen.

Only thing you can do is report it as stolen to the police with all details you have about it.
Make, model, serial number (could be on the invoice, or ask the vendor), perhaps even a list of installed software.

Without tracking software, your chance to get it back is about 0%.
