Newark's not listed, so it's not a legal route for that TPA-LAX fare (and if it's not legal for that fare, I'm pretty sure it's not legal for any discounted fares. :-)
I've definitely seen the online SDC tools offer routings that aren't valid per the fare rules, but I'd be shocked if that particular option arose.
Except EWR-LAX/SFO (i.e. PS flights) actually are usually called out as NOT allowed. For example I just pulled up HAA0UPKN for 8/18 TPA-LAX
" THE FARE COMPONENT MUST NOT INCLUDE TRAVEL BETWEEN EWR
AND LAX."
The other problem you'll run into trying to SDC onto a PS flight is the fare bucket. EWR-LAX/SFO is BF - no 'A' is even offered so no chance app even gives it as an option.
