Is it possible to have 64.5GB log files in Ubuntu? Can I delete those files? My laptop is dual booted and the Ubuntu partition is only 100GB.

You must not remove the entire folder but you can remove "Old-Packed" log files without harming your system.
For a typical home user, it's safe to remove any log file that is compressed and has a .gz extension (as you can see in the picture).
These compressed log files are old logs that are gzipped to reduce storage space, and as an average user, you don't need them.
It is generally safe to delete log files. The only disadvantage associated with doing so is that you may not be able to examine the log, if you're troubleshooting some other problem later. Since new logs are automatically generated, even this disadvantage is short-lived.
Most logs are deleted automatically (after being rotated by compression and renaming, and kept a while in that archived format). If you have a log that's expanded faster than Ubuntu is deleting it, it's unlikely that you'll experience any problems from deleting it manually.
However, if you have a log file that's 22 gigs in size, something very strange is happening, and it would be worthwhile to investigate that. I recommend editing your question again to include a link to the Ubuntu Forums thread you're talking about, and also to include the full name of the 22 GB log file.

Yes, but do not. EMPTY them instead of deleting. Deleting files from /var/log/ requires the file to be unused and most log files are open. In theory deleting the file might crash the service that uses this log. Not a big issue unless you are hosting something that can not have downtime.
You can empty it with:
Another note: please do not empty them without at least examining why these exists. Those logs will return and return and return. Fixing the issue that is being logged will keep those logs small.
