甲公司委派业务员张某去乙公司采购大蒜，张某持盖章空白合同书以及采购大蒜授权委托书前往。
　　甲、乙公司于2010年3月1日签订大蒜买卖合同，约定由乙公司代办托运，货交承运人丙公司后即视为完成交付。大蒜总价款为100万元，货交丙公司后甲公司付50万元货款，货到甲公司后再付清余款50万元。双方还约定，甲公司向乙公司交付的50万元货款中包含定金20万元，如任何一方违约，需向守约方赔付违约金30万元。
　　张某发现乙公司尚有部分绿豆要出售，认为时值绿豆销售旺季，遂于2010年3月1日擅自决定与乙公司再签订一份绿豆买卖合同，总价款为100万元，仍由乙公司代办托运，货交丙公司后即视为完成交付。其他条款与大蒜买卖合同的约定相同。
　　2010年4月1日，乙公司按照约定将大蒜和绿豆交给丙公司，甲公司将50万元大蒜货款和50万元绿豆货款汇付给乙公司。按照托运合同，丙公司应在十天内将大蒜和绿豆运至甲公司。
　　2010年4月5日，甲、丁公司签订以120万元价格转卖大蒜的合同。4月7日因大蒜价格大涨，甲公司又以150万元价格将大蒜卖给戊公司，并指示丙公司将大蒜运交戊公司。4月8日，丙公司运送大蒜过程中，因山洪暴发大蒜全部毁损。戊公司因未收到货物拒不付款，甲公司因未收到戊公司货款拒绝支付乙公司大蒜尾款50万元。
　　后绿豆行情暴涨，丙公司以自己名义按130万元价格将绿豆转卖给不知情的己公司，并迅即交付，但尚未收取货款。甲公司得知后，拒绝追认丙公司行为，要求己公司返还绿豆。

甲公司能否以未收到戊公司的大蒜货款为由，拒绝向乙公司支付尾款？为什么？
