Can i download and install a new lens profile with an older version of lightroom?

[#1]

I have an older version of lightroom (release 7.5). I would upgrade to the newest version, but my computer system will not support it so i am stuck on this until i spend £1000 to upgrade my computer. 

Meanwhile, i have the new Tamron 17-28 (f2.8) and Tamron 28-200 lenses on Sony E which i would like to correct distortion on raw files images that i have. 

Am i able to download and install individual lens profiles on this older lightroom version?  If so, where can i find these profiles and where should they be stored on my Mac system (OS X El Cpaitan v10.11.6)?
