No, there is no way how to launch another app in WP7.
You can use only predefined choosers or launchers, but you cannot launch 3rd party apps:

In Windows Phone 8 however you can use so called protocol handlers, so for example if you wan to launch Skype with selected user, you can use something like:

await Windows.System.Launcher.LaunchFileAsync("skype:myskypeid");

This functionality is currently not widely used, so we should see more usage of these launchers in the near future. These Uri shemes are already working and you can use them:
