Yeah, that would work. Aneutronic fusion or M-AM annihilation would mean you just deal with pure gamma (assuming perfect confinement of charged products). Most papers on gamma effects on carbon nanotubes are paywalled (from a cursory google at least), but from the abstracts it sounds like gamma bombardment in a vacuum causes defects (and interestingly, cross-linking) in SWCN and MWCN, but only above a certain energy (>~100kGy), so wrapping the tether in a blanket of Lead/DU/something dense to sap the gamma pulse energy should do fine for long-life tethers.

If you've got ample sunlight, you can skip the solar cells and illuminate your plants/algea/whathaveyou directly (using chevron mirrors rather than glass/saphire/etc to avoid irradiation). Though as wryt mentioned, if you are far from a nearby star then you'll have to provide the lighting from on-board power.
You might get marginally better efficiency from a purely chemical CO2scrubber+O2generating process*, but plants have the benefit of occasionally providing something less monotonous to eat too, and being generally nice to walk/float about in when confined aboard a tin can for a few centuries.
* Per weight, which is generally all that matters in space. If you really need to keep volume down for some reason, then direct chemical is the way to go.
