Yes and no. I’ll discuss some safe ways to continue using Windows 7 after January 14th, 2020 which is when the last security updates will be released and is the official Microsoft End of Support date.
As long as you do not connect to the Internet then you still can continue to use Windows 7. Don’t even think about connecting just long enough to update your Anti-Virus software.
Options: 1) Convert your Laptop or Desktop to a Dual boot Windows 7 and Windows 10 computer. In Windows 7 disconnect your wireless access to your router. In Windows 10 you can connect safely to the Internet as long as you have a top notch / well rated Anti-Virus installed.
2) Desktop users can also dual boot 7 and 10 but usually connect to the Internet via a LAN / Cat cable. If you have easy access to the back of the desktop PC you can disconnect the LAN cable prior to booting to Windows 7. Another option is to remove the LAN cable and connect to Windows 10 via a USB Wireless network adaptor. Windows 7 may detect the adaptor but as long as you don’t attempt to connect by entering the password for you router’s wireless broadcast ID you’re safe. The adjustable antenna will help you obtain the best signal strength.
Either way (Laptop or Desktop) it would be wise to check your disk drive’s “SMART” values, especially older computers as the drive may be near the end of its life. If this is the case consider replace that old and failing hard drive with a Solid State Drive (SSD) you’ll see a noticeable performance increase.
Anti-Virus Software: Better grade AV software offer a Disk or partition scan option which will allow you to scan the Windows 7 partition on you disk drive from time to time. If you need to transfer file from Windows 7 to Windows 10 you can use a USB Flash drive or if you disk drive is large enough create a 3rd partition and name it “Shared”.
Image Backup Software: Before you start to convert from a Windows 7 only to a Dual Boot 7 and Windows 10 PC for safety reasons create an Image Backup of the entire hard drive. Should something go wrong during the process you can always restore Windows 7 and try again.
Consider making frequent image backups after you have created your dual boot computer. On my computer I create a weekly “Full” image backup and a daily “Incremental” (an Incremental only takes a few minutes) backup. That’s seven backups per week (One set) and you can specify how many sets you may what to keep with the oldest set being delected.
That a look at Acronis True Image, EaseUS Todo backup, Paragon or Macrium Reflect.

Note: In order to create a Dual Boot computer you first must “Shrink” the existing Windows 7 partition to make room for the Windows 10 partition you will create and format prior to installing Windows 10.
Sometimes Windows 7 “Disk Management” cannot shrink the Windows 7 partition enough to install Windows 10 on a reasonably sized partition due to the present of locked (in use) files near the end of the Windows 7 partition. In this case you will need to install a third party partition manager such as “Mini Tool Partition Wizard Free version”. Partition Wizard is graphical and easy to use. https://www.partitionwizard.com/download.html
