Is it possible to crop CR3 file and save as (export) as CR3 file in Lrc?
I want to send cropped CR3 file to my friend to get help but I want to keep my photo composition.
Just for study only.
Usually I edit CR3 file to tif file and then export to jpg file.

I found a way to export to DNG file but not CR3.
Are they the same?

You can export as Original + Settings, which will give you a copy of the original CR3 plus an XMP sidecar file which will contain your edits (including crop). Assuming your friend also has LrC, the edits will be applied when they import the CR3 (but they can always reset the image back to the original version).

CR3 is a proprietary format owned by Canon. Other companies such as Adobe do not create or update such proprietary RAW files except for a few minor things like changes to capture date.

DNG (Digital Negative) is an open source format created by Adobe which acts the same as a RAW file and is considered as a RAW file type.

Depending on your friend's SW, you can just save your metadata from LrC (Menu: Metadata -> Save metadata to file) which will creat an XMP file in the same fodler as the CR3. You can then send your friend both the origuinal CR3 and the companion XMP file. If your friend's SW know to look for the XMP it will contain the cropping info and (s)he'll see the cropped version. Most modern image editing and viewing SW knows to look for XMP files. Alternativly you can export as a DNG or TIff both of which will retian pretty much all the info from the original CR3 (depending on export settings) as well as the LrC changes

As far as I am aware, to have this work properly your friend will need to be using the equivalent version of LrC or PS / Adobe Camera raw to apply the edits you have made in LrC including the crop.

Not necessarily. XMP is a publicly defined standard for capturing edit information for transport across applications and computers. Many image editing and display software products adhere to the XMP standars and if they see the XMP file will take it into consideration when rendering the CR3 file for display or printing. What is a bit weak though is that not all SW treats the edits the same way. For example if you bumped up the saturation by a value of "3" it gives you a certain look. However some other SW may give a slightly more or less saturated look with a value of 3. But in general most decent SW is pretty close. However, as your question was related to cropping, that should be pretty accurate as 4000 pixels is 4000 pixels in everybody's SW. You just need to ascertain if the destinaton SW is XMP compliant or not.
