Nope.
Dynamic Queue has only ever been the ability to take 1-5 people together in a Ranked game. It's the name for a feature new to Ranked that has always existed for Normals.
The New Champion Select is picking primary/secondary roles, pick intent, bans distributed to three different people on the team, etc.
The two are very separate features that were released at the same time. If you mix up the names you'll confuse a lot of people on the boards or be very confused yourself. There are many people who dislike Dynamic Queue but love New Champion Select.
