Hell no! That's about 30 min over minimum connect time on a single PNR.
TG non-stop LHR-BKK isn't that cheap, either. Looking at AGP-BKK for a random week in February, you can do it via Helsinki for €1,875 (and earn 560 BA tier points). Meanwhile the TG fare alone is £2,500 from London. And of course you still save yourself the timings and decrepit aircraft of BA9.
