Anecdotally this was the case for a large number of what I think of as lower end 286 mobos. With the odd case, particularly later models that gave you more ability to change all the BUS speeds to variety of different options.  Related to oscillator speed, derivitives of that, CLK/2 CLK I had one that would even let you use the KB strobe.. 

Given the ISA bus was around so long, you had to be a little careful, as usually older cards tended to fail when driven to hard.  Given that 10Mhz is near 200% spec its a big ask for an old card with slower components.
