Shouldn't work out of the box with any DOS games because you need the link files to launch the games and the paths are absolute, so if you move the game the links become invalid. But, as Thiev suggested, you could probably create batch files that automatically launch DOSBox with the correct parameters adjusted to the current directory (instead of using link files). Would take some effort to set that up, though, unless someone like Thiev gives you at least an example batch file. Because GOG's naming conventions include the game's title in the configuration files' names you'd sadly always have to make at least some small adjustments.
