Yes, you can reimburse a 2024 expense from a 2024 FSA, even if you wait to submit the claim until your account is "filled up" enough to cover it. (You can't reimburse a 2023 expense from a 2024 FSA.)
Let me add a note that you might not have to wait, check with the plan administrator. Both of my past employers when I had FSAs would reimburse up to the amount I had set, even if I submitted the claim before the money was deposited. (i.e. if I deposited $100 per month, I could claim $1200 in February and they would still pay it.) Your employer might not follow this but it would not hurt to ask.
