NO. The game doesn't begin with the assessing of the technical foul. It begins when the ball is made live for the administration of the first FT.
The only permissible substitutions prior to that FT is to insert a shooter or to replace an injured or ill starter.

Once that first FT is attempted, then substitutions may be made, except any starter who was pulled cannot re-enter. Those individuals must sit a tick.
