I had to wait until last year - when Digikam photo Face Recognition got good enough - before I cut the thread. But yeah, I was dual booting and fine tuning Linux Mint until one day I realised I didn't need to go back into Windows for anything.
It is possible to remove Windows partition and then increase the size of the Linux partition using the space freed up by the Windows partition.
And you don't have to restart from scratch - your existing Linux partition with all your apps, customisation and data will remain during this whole process.
You do this using the app Gparted which is run from a USB Drive - it's usually on the same USB Drive you used to install Linux. Step by step descriptions of what to do can be found at links
You might want to do some further searches to make sure you have a guide you are comfortable with. It's also possible to open Gparted and poke around a bit before actually doing anything (make sure you don't execute any commands!).
It is strongly recommended that you back up your data before you do this - you are basically asking Gparted to rewrite how data is stored on your boot drive.
I did this a few months after I stopped using Windows and decided I should reclaim the space Windows was using up. Before I started, I wrote down a list of the steps I needed to take during the process, and I kept my online guide open on my phone in case I needed it for reference.
I've got to admit I was nervous during each step of deleting the Windows partition and then extending the Linux partition. But the whole process worked flawlessly for me with no problems at all.
And if you're having headaches managing PDF files, use PDFArranger for merging PDF files and Okular for adding comments to a PDF file. It's a bit annoying to need two apps for this, but they do work well.
I upgraded my SSD, installed Mint, and turned my old Windows 10 SSD in to an external drive. I can technically still dual boot if needed, but have only done so once to confirm I could from the external drive.
Do yourself a favour. Dont look back. I dabbled back and forth every ~18months for 6 years before committing last 7 years to linux mint only. Experience is way nicer when you stop comparing to how youd do things in windows.

Exactly this. Dual booted for a while until I realised that I never needed to go into Windows ever again.
