However oblivious you think cis people are, you're underestimating. You absolutely can do that for a long time, and it's very common.
I would recommend against binding, though, because it can interfere with breast development (assuming that you want that development ofc). It wouldn't even be a concern for a while anyway though- I'm on 1.5 years HRT and my tits are only just starting to get big enough that I would even have to consider that if I wanted to hide them, and if I DID want to hide them my clothing choices might be enough to do that. And I'm led to believe my tits are growing faster/more than average.
The real limit here is how long you actually WANT to stay closeted. I planned to boymode for a long time (I had a wedding planned for 8 months after I started and I was even considering boymoding for that), but once I started transition in earnest I found I really couldn't stand being closeted. And I say this as someone who presents pretty masc by choice!
