What and how to install on laptop with tiny memory?

Hello! I am beginning my Linux exploration, and have an old laptop, I am willing to sacrifice as a learning device. The problem is: it has only 30 Gb of SSD memory (non-upgradable) + 30 Gb SD Memory card.

As far as I know, in Linux, you can't just put some programs on the SD card to reduce load of the main memory, but maybe there's some way to partition it, so the card is assigned in such a way, that it will be used by system?

Also, which distro is lean and beginner friendly? I want to try Fedora, but it Google shows I will need 40 Gb root partition...

Thank you for your time and attention!

P. S. Laptop specs are:

• ASUS TP200S
• Intel Celeron N3060 (1.6 GHz)
• 4Gb RAM
