Generally, no. You can’t install Linux onto a Windows filesystem (NTFS). What you can do is one of these things:
Back up the files you care about (Desktop, Documents, Downloads, whatever) in Google Drive, Dropbox, a thumb drive or anywhere else that you can access later. Then you can tell the Linux installer to wipe Windows and afterwards put your important files back.
If you have a spare SSD you can put Linux on that. Then you can access the Windows drive from Linux. You might have to install an NTFS driver first, and you will definitely need to configure Windows to shut down properly instead of secretly hibernating, because that leaves the filesystem in a weird state and Linux won’t be able to open it.
If you don’t have a spare SSD you can still do the same trick by shrinking the Windows/NTFS filesystem and installing Linux in the now-free space on the same drive. Among Sysadmins shrinking filesystems has a bad reputation because at least historically it could (rarely) fail and destroy all your data, so I would not recommend you do it but it is possible and in most cases it works without issues.
Each of these comes with some risk - You might forget to copy over important files onto your thumb drive, or you might make a mistake in the Linux installer and accidentally delete Windows when you didn’t mean to. That said you should already have a backup strategy, because your PC could also just spontaneously die and lose the data even if you do nothing. If you have backups and you’ve tested them to know that you really can restore all the files you care about, then even that first option stops looking very scary.
