It’s not clear. The IRS has not issued any official guidance on this very common question as yet. The law says that the policy must be established, or considered to be established, under her business. The IRS has decided that premiums for Medicare qualify for the self-employed health insurance deduction (CCA 201228037); clearly, Medicare is not a plan established by the business but is treated as “considered to be established.” It could be argued that COBRA should be similarly treated as self-employed health insurance and that the premiums should be deductible from gross income (rather than as an itemized deduction) as long as she is otherwise qualified (i.e., she is profitable and does not qualify for any employer-subsidized health coverage).
