You can and it will work in only in one situation -
The company and the said role/team needs a person who acts like pathfinder and you were the best they could get to fit that bill in the time period they have at hand.
Pathfinder is simply the person who will decide what needs to be done.
So this is a rare case situation where all stars align.
An approach to find such events where stars align - follow fundraise cycles of company, follow the employee migration patterns, back channel talk to employees to gauge their level of talent and skills, befriend them so they recall you when there is a discussion of hiring a senior in their company.
Not a lot of people can do what it takes. Not because it's difficult but coz it's rare.
Faking that you are matured enough irrespective of your yoe is simple part. Talk like a VP or architect would.
