Yes. But it is an offset into the unpacked raw HTML content of the MOBI.

You can obtain the raw HTML contents of a MOBI file (what location numbers index into) using
kindleunpack. You will also have to deal with DRM for many books.

Kindle locations are approximate indexes into the book, good enough to get you to the right screen of content. It is hard to tell whether or not that will be good enough for your purpose.
There is a recent thread in the Amazon Kindle forum,
Extract notes from "My Clippings.txt", started by someone who wants to do something similar. See the post from me in that thread for information on how locations map to KF8/AZW3.
KFX format, which is used for most Amazon-purchased books on newer kindles, would take a lot more work to deal with.
Good luck.
