This is a great question that I think happens fairly frequently. From your question, I wasn't certain if you were saying the recruiter was a corporate recruiter for the company or an agency recruiter who had the company as her client. If you interviewed with the corporate recruiter, you want to make sure you reach back out to her and let her know that you saw a similar role on LinkedIn and applied and wanted to let her know. Since the corporate recruiter and the hiring manager are working together, you want to ensure they are on the same page with your candidacy and the corporate recruiter will appreciate your honesty. It will also provide you with a way to follow up on your candidacy for the opening. If it is an agency recruiter that you interviewed with, it can get a trickier. Some agencies have contracts set up with clients that once they present a candidate to them; the client can only work with the candidate through the agency for a set period of time. If this is the case, then the hiring manager will not be able to work with you directly. If the agency recruiter doesn't have a contract with the client, then you are free to reach out directly to the hiring manager on LinkedIn. I would recommend that you let both the hiring manager and recruiter know that you are very interested in the opportunity and aren't sure if it is the exact same role you already interviewed for, but you are very interested in the company and the role.
All the best!
