Yes you can! You can go "All in" with whatever you have in front of you.
Just make sure to loudly declare ALL IN and use both
hands to push your micro "stack" in as if it was a mountain of chips
A more important note..
"A player can win all dead money (antes), plus no more than their own all-in amount from each opponent's betting contributions."
This means if you put less than a blind in you still win ALL the antes, but you only win bets from
each player that match the amount you put in.
So if an 8-player table has a
0.25 BB ante and a player has only
0.1 BB left after the ante, that player is eligible for the
2BB in antes. They can also win up to
0.1 BB from each player's other betting contribution(s).
