There is a 4.0.3 ICS ROM but it's in an alpha stage. It's just for testing purposes and not meant to be used as a daily driver. Since it exists, yes, it's possible to run ICS on the Legend, and it will most probably be released for it when CyanogenMod 9 comes out.
The other stable ROMs are based on the latest version of Gingerbread (2.3.7), i.e. non-official CyanogenMod 7.2.0.
Also, official CyanogenMod 7.1.0 for HTC Legend exists, and is the same version (2.3.7) but has a few less features than 7.2.0, obviously.
That is the latest
stable version of Android that you can get at the moment.

Since you're new here, no problem, but next time search before posting. You could have got all the info I've given you by yourself if you had just googled 'htc legend development' or 'htc legend roms'. Beats posting a question and waiting for an answer!
Click thanks if I've helped you.
