Nope, you cannot. Closed-source software is as important as open-source, because some things will simply never be possible to make with an open source business model. We'll never get an open source edition of Photoshop or AutoCAD, so Linux will remain simply unusable as a daily driver to people who depend on it, hurting OS adoption. Even if you could theoretically recompile, compiling old unmaintained code on new distributions is a huge pain. Broken/removed API calls for every external library you include will be a huge pain, because they will need to be fixed manually. That's assuming the library still exists, and you don't have to port your software to some entirely new library that suddenly means you have to restructure or refactor the entire codebase to use it. That's not trivial. You need a programmer to do that, which is outside of reach of most average users.
