The Hammers' 19-goal top scorer missed the 2-0 quarter-final first-leg defeat in Germany and Sunday's Premier League loss at home to Fulham with a hip injury.
Bowen took part in training at West Ham's Rush Green HQ on Wednesday morning and hopes are high that he will be available against a Leverkusen side unbeaten all season.
Goalkeeper Lukasz Fabianski said: "I was pleased and we were all pleased to see Jarrod training with us.
"Jarrod is obviously a very important player for us, hopefully he will be able to help us as well."
Manager David Moyes said: "It was great to see Jarrod out there.
"We're not sure yet. I would never risk a player if thought they were injured but you always want your best players back in, your goalscorers as well, and Jarrod has been that this season."
The news is a major boost to the Hammers as they attempt to inflict a first defeat of the season on Xabi Alonso's Leverkusen.
But they will be without key Brazilian midfielder Lucas Paqueta through suspension after he was booked in Leverkusen.
Left-back Emerson Palmieiri is also suspended while centre-half Konstantinos Mavropanos is a doubt.
