To make my television mount look clean I ran a new extension cord, the tv plug and the cable wire through a wire management system that sticks on the wall. The extension cord is plugged into a 2 foot surge protector which is taped to the back of the tv as is the cable box ( it's very small). The only thing plugged into the surge is the cable box.
Is this safe? Nothing is run through the wall.

Technically, this is not okay. Wiremold® and other similar products are not typically listed for use with power-supply cords, cordsets, or other similar cables. They're designed to contain data, communications, and audio video cables. See this answer for more details.
Check the manufacturer's documentation, to determine exactly what types of cables are allowed in the specific product you're using.
As for plugging the surge strip into the extension cord, that's definitely not allowed. There should be a label on the strip, or in the documentation included with the strip that says not to plug it into another strip of extension cord.
The common solution to this problem, is to use a kit designed for this, like the one described in this answer. Though with a system like this, you'll have to cut holes in the wall.
If the wire management channel is a listed raceway, then you shouldn't be running power and communications cables through it together. Unless the raceway is divided for the entire length.
