No, the Turkic languages of Russia often have very similar phonology, but the Stalin-era language planners intentionally chose different ways to orthographically represent identical features across the languages.

For example, Turkic languages typically feature front/back vowel harmony where stops are velar before front vowels and uvular before back vowels. This is represented differently in the Stalin-era Cyrillic orthographies for Karachay Balkar (к/къ), Kazakh (к/қ) and Tatar (just к with the following vowel letter showing the distinction). Bashkir neighbors both Tatar and Kazakh and is mutually intelligible with them, and it doesn’t differ at all in this feature, but its orthography was given к/ҡ just to make it different from the other two.
