The 4-digit addressing is dictated by the engine, not the Base 3.
So, no you have to use 2 digits with TMCC. All new Legacy engines going forward will have 4-digit addressing.
Older engines you must use 2 digits.
Nothing has really changed on how they are addressed, except now in the app you have the option of selecting the engine off a roster in addition to typing in the engine ID and hitting start.
On the Cab 2 (with 990 Base 2) you could assign a four digit cab number in addition to a two digit address.

Correct, you can use the 4-digit cab number to select engines using the Legacy #990. The BASE3 4-digit addressing is an expansion of the TMCC ID, but of course, only in new engines from around 2023 and later.
Right. The OP asked if you can assign a 4 digit cab number to TMCC locos with the Cab3/Base3 the way you can with the 990.
I think it's a good question.

Thats a good point. I think the question was assumed he meant the engine TMCC ID, but maybe he meant the road number label.
You can only assign a 2-digit ID (which is used for addressing the engine) on TMCC engines, but in the road number you can label it with 4. The road number is not where the 99-engine restriction was though and doesn't have anything to do with the control of the engine.

The question is confusing but I think you covered it.

The road number indeed wasn't where the restriction was, that's true. However, you can use the 4-digit road number to select the engine for running with the CAB2, so as once you have a TMCC ID assigned, you can select the engine with that road number.
Not as neat as the real 4-digit TMCC ID, but it gets the job done in a lot of cases. 
In most cases it's fine, I'd submit.
I don't have 99 engines. And even if I did, I could never run them all. I really doubt I have any with the same road number either.
I have several engines with a similar "road number" or "cab number", for instance 626 is used for a Great Northern Geep my shorthand way of addressing the engine using 2 digits is 26 but the new Lionel Lines Berkshire 726 (Lion Chief +2) The problem I encounter is in using the last 2 digits, or 26. I had hoped the new system would solve this, but I guess it will only help with engines going forward. I wanted to use the cab number as a shorthand way of remembering the engines as I am lazy and don't use the trains as much as I should.

One thing to keep in mind, IF, you are using the Base3 and the Cab3 App (not a handheld remote), then you don't even need to think about IDs anymore. You could start with ID 2 and work your way up because with Rosters, you know longer need to remember an ID. You just select the engine off the roster by its name or in your case its road number. Remembering ID's or trying to make a unique ID out of the Road number goes out the door. The Rosters are one of the absolute best features of the Cab3 App. Think of it like MTH's system where the engine gets an ID, but you don't have to know it to find the engine in the list.
Thank You. Sean. I will give the App a try.
