Its unclear what you mean by "on a i686 OS"; if you do a straightforward install of OpenSuSE (of whatever version), that would be the OS; if it is the OS (and putting aside things like virtualisation, which I assume that you don't mean) and therefore it can't be a problem that it is different from something else.
Assuming that you mean "installing the openSUSE 11.1 (i586) DVD on a i686 hardware
", the answer is no, that will not cause problems.
