Yes & no.
You can't completely wire a 2 way switch using T&E, as that would involve using the cpc (earth wire) as a live conductor, a huge no-no.
However, you can use T&E as strappers (links) between switches.
In older two-way circuits, it is very common (excuse the pun) to find a live feed at one switch & a switchwire at the other, the two linked by a run of T&E.
In this scenario, it is possible to "wire" a two way switch by piggy-backing off a live common to an adjacent common terminal & connecting twin & earth to the L1 & L2 terminals of that switch.
