You could install an application like

on both computer that will let you remote control your home computer from your work computer. There are alternative options like TeamViewer or even VNC Connect.
You'd need to leave your computer at home switched on and you'd need to check your employer's IT department if there are restrictions about you to installing 3rd party programs yourself on a work computer. But it's a simple solution and means you can do everything you normally do at home, while working remotely. Because in effect, you are still working on your home computer.
Failing that, you could just install RenPy and its default text editor (currently Microsoft Studio Code) onto your work computer. Copy your game onto a memory stick or something and then to the laptop(?) and so just carry on working.
For that matter, RenPy scripts are just basic text files. You can edit them with Notepad as a bare minimum (bad idea) or again, VS Code (without RenPy installed) or Notepad++.
All this comes with a risk. It's easy for your
.rpyc
files to get out of step with the base game - if you maintain the game in two places. You have to be very careful to only copy the
.rpy
files back to your home computer and never the
.rpyc
files. RenPy has mitigation for this sort of problem built in these days, but it's still a risk.
Or you could use an drive/folder synchronization tool like OneDrive or Dropbox to keep a folder on your work computer synchronized with your RenPy folder on your home computer. You'd still need a text editor, but the changes would be automatically kept in line.
The other consideration is how well you'll be able to work with only the script files. The images are important and whilst RenPy will work (and therefore allow you to continue developing) without them, it is a pain.
