Maybe initially, but there definitely were still 486s with Turbo buttons that would throttle the machine to some frequency much higher than 4.77MHz (or just disable the cache). I had one! And apart from that, CPU generations have vastly different speed profiles if you kept them at the same frequencies (which is mostly theoretical, clocking a 486 at 4.77MHz, while not necessarily impossible, might turn out to be quite a project on consumer hardware).
Turbo buttons were always a shaky proposition. They might have worked okay-ish with the original AT to slow the machine down into a somewhat fitting range to play older games, but probably quickly devolved into some show-offy marketing ploy ("look how fast it goes if I press this!").

Quite a project indeed, but possible with the right motherboard -- as an amusing side note, there is a very strange sub-sub-sub-genre of computer enthusiasts who enjoy the challenge of installing various Windows versions on the slowest possible systems that will run them: https://www.winhistory.de/more/386/winq.htm https://www.winhistory.de/more/386/winq.htm They've managed feats like running Windows XP on a 4 MHz Pentium Overdrive and Windows ME on a 3 MHz 486SL (that one takes 1 hour and 10 minutes to even boot)
