Yes. I've done so several times.

No. There no need to move data from the LV around. The LV just gets
a couple of new PEs assigned just as with non-striped LVs. Only the
mapping of already allocated LEs to PEs is modified, e.g.
LE PV PE LE PV PE
00 /dev/sda1 00 00 /dev/sda1 00
01 /dev/sda1 01 01 /dev/sda1 01
02 /dev/sdb1 00 02 /dev/sda1 02
03 /dev/sdb1 01 03 /dev/sdb1 00
04 /dev/sdb1 01
05 /dev/sdb1 02
Look at lvdisplay -v before and after running lvextend.
