Can I put my WordPress theme files in another folder?

Currently my folder structure looks something like

...\themes\MyTheme
  - \lib
  - \src
  - index.php
  - style.css
  - more theme files
  - .gitignore
  - README.md
  - many other non-Wordpress files

I’d like to change it into something more like

...\themes\MyTheme
  - \lib
  - \src
  - \wp - Pretty much all my theme's .php files
  - .gitignore
  - README.md
  - many other non-Wordpress files

The answer is yes. Like @Kvvaradha mentioned in his comments. If you put

header.php
footer.php
index.php
functions.php
style.css

must be in /wp-content/themes/your-theme-folder. And other your library, components and includes could be put anywhere that you prefer. But, make sure files and folders structure are flexible. Good luck in your codes 🙂
