Not that I'm aware of. You can generate an index with the following code (which takes all of the files in the Documentation/English/Tutorials
folder, makes them a little more readable (it doesn't take the actual tutorial names, just tries to make the filenames more readable), and lists hyperlinks to them):
pretty[str_] := Hyperlink[
StringReplace[StringRiffle[StringCases[str,(_?UpperCaseQ ~~ __?LowerCaseQ)]], (Capitalize[#]->#)& /@ {"for", "to", "and", "on", "as", "of", "in"}],
"paclet:tutorial/" <> str
];
SetDirectory[$InstallationDirectory <> "/Documentation/English/System/Tutorials"];
pretty /@ FileNames[] // Column
