Not per se, but that doesn't mean it isn't possible to approximate it. The MOBI format does support forcing a page break at a particular spot, so what I would do is this:

<div class="nobreak">
content here
</div>

@media amzn-mobi
{
    /* MOBI7 styles */
    .nobreak {
        page-break-before: always;
    }
}

@media not amzn-mobi
{
    /* KF8 styles */
    .nobreak {
        page-break-inside: avoid;
    }
}
