You could probably get away with it. What you should do is just thoroughly read the terms of service pages for this website. But if you intend to try to make money here you will also need to have the gist of the terms of service for Google Adsense down too.
For instance - you can never link to a website which sells guns. And you obviously can not link to a website which is pornographic in nature. Those kinds of things. But you want to link to a site where someone downloads an app. I would seriously doubt there would be a problem with that so long as that is what the website is about.
