I want to add 15 days to all my active subscription users for free.
for example if a user expiration date is 1 April, I want to change it to 15 April by API or from Google Play Console.
is it possible ?

Yes you can, if you already integrated in-app promotions in your app.
You can create promotion codes to give selected users an extended free trial to an existing subscription SKU.
Check out the documentation to know how to apply.
You can implement this functionality by using https://developer.android.com/google/play/billing/subscriptions#defer from the server side, assuming you store and know the information about active subscriptions
