You should be able to install/run LM 13 without a problem. KDE is a bit of a heavyweight compared to Gnome, but I run LM 13 (MATE) on an old HP laptop with only 1 GB Ram, and an Intel M (2 G HZ) processor. Cinnamon was too resource hungry, KDE was not released when I installed it; MATE runs with no issues. Good Luck
