Hello Aspirant,
Yes PCB students can do B.Tech. as well if they have Mathematics as an additional subject but only in some places because not all entrance examinations allow the candidates having Mathematics as an additional subject in 10+2.
Because for engineering courses, commonly Mathematics and Physics should be there in 10+2 as compulsory subjects so if you don't have that then you can do B.Tech but at very limited places.
I hope you got the point.
Good Luck!!!
