I don't think so. Most scholars, turkologists and linguists classify the Chuvash language as Oghur Turkic language just like Khazar, Avar and Bulgar languages but they are not so sure about the Hunnic language
Here is something interesting about Chuvash language
Chuvash (Чӑвашла,
Čăvašla; IPA:
[tɕəʋaʂˈla])
[2] is a
Turkic language spoken in central
Russia, primarily in the
Chuvash Republic and adjacent areas. It is the only surviving member of the
Oghur branch of Turkic languages. While many Turkic languages demonstrate
mutual intelligibility to varying degrees, Chuvash has diverged considerably from the other languages in the group
Chuvash is the most distinctive of the Turkic languages and cannot be understood by speakers of other Turkic tongues. Today, Chuvash is classified, alongside
Khazar,
Turkic Avar,
Bulgar, and (possibly)
Hunnic, as a member of the
Oghuric branch of the
Turkic language family. It is the only language of this family which is not extinct. The conclusion that Chuvash belongs to the Oghuric branch of Turkic arises from the reasoning that the vocabulary shows the language to belong to the
r- and
l- type which is typical for all languages of this branch. The rest of the Turkic languages (Common Turkic) are of the
z- and
š- type."
[13]
Since the surviving literary records for the non-Chuvash members of Oghuric are scant, the exact position of Chuvash within the Oghuric family cannot be determined.
Formerly, scholars considered Chuvash not properly a Turkic language at all but, rather, a Turkicized Finno-Ugric (Uralic) language.
