Oh, goodness, yes.

You could try
the OtherBlog plugin (that's probably the easiest), or if your site uses PHP or SSI, you can create a new index template in the blog that the information will be coming from
CODE
<MTEntries lastn="3">
<a href="<$MTEntryLink$>#<$MTEntryID pad="1"$>"><$MTEntryDate format="%B %e, %Y %I:%M %p"$></a> <$MTEntryExcerpt$> <br><br>
</MTEntries>
<br>
No DOCTYPE, no HTML, just the plain-vanilla MT tags. This makes the date a link to the entry and shows the entry excerpt; you could take the excerpt out and replace the date with the title tag. I include this using PHP in the destination blog's sidebar.
See an example of this template in the sidebar here.
Does that help?
