You can accomplish this using SolutionFolder interface:

Project project = getSolutionSubFolder(solution, "SubFolderName");
if (project != null)
{

    folder.AddFromFile("yourProjectFilePath");
}

Where getSolutionSubFolder method looks like this:

private static Project getSolutionSubFolder(Solution2 solution, string subfolder)
{
    return 
        solution
            .Projects
            .Cast<Project>()
            .FirstOrDefault(
            p => string.Equals(p.Name, subfolder, StringComparison.Ordinal));
}
