How does this actually manifest - do you want to unilaterally change your title on your resume? are you going to introduce yourself to people differently? is it just you in front of the mirror calling yourself senior? (if it's that, you can do it now) What you call yourself doesn't matter too much, it's more about what your company calls you, and even that varies a lot - there's people with less experience than you who have a senior title and people who have been programming for many years who've never been called senior and it's not a big deal to them. Basically, land a senior position, then you can.
