Is this possible - Linking > Google Analytics (Segments) and Adobe Target (A/B Testing)?

There really isn't an official integration between Adobe Target and Google Analytics. You can always use something like the following after you fire your global Mbox to send Adobe Target activity data to the Google Tag Manager datalayer--or modify it to send Google Analytics events directly if installed on page. 

document.addEventListener(adobe.target.event.REQUEST_SUCCEEDED, function (e) {
    var tokens = e.detail.responseTokens;

    if (isEmpty(tokens)) {
        console.log("No active Adobe Target activity.");
        return;
    } else {
        var uniqueTokens = distinct(tokens);
        uniqueTokens.forEach(function (token) {
            window.dataLayer.push({
                'event': 'adobeTargetMetaData',
                'CampaignName': token["activity.name"],
                'CampaignId': token["activity.id"],
                'RecipeName': token["experience.name"],
                'RecipeId': token["experience.id"],
                'OfferId': token["option.id"],
                'OfferName': token["option.name"],
                'MboxName': e.detail.mbox
            });
        });
    }

    function isEmpty(val) {
        return (val === undefined || val == null || val.length <= 0) ? true : false;
    }

    function key(obj) {
        return Object.keys(obj)
            .map(function (k) {
                return k + "" + obj[k];
            })
            .join("");
    }

    function distinct(arr) {
        var result = arr.reduce(function (acc, e) {
            acc[key(e)] = e;
            return acc;
        }, {});

        return Object.keys(result)
            .map(function (k) {
                return result[k];
            });
    }
})
